Arrays – FREEBIE!

Math, Task Cards, TPT
I began teaching arrays this week to my kiddos and they have been loving it. Some have already figure out how it’s connected to multiplication and basically is multiplication and others…. well we’re not there yet.
 
Since we are doing arrays, we have had a lot of practice with creating them from knowing the rows and columns and identifying the arrays.  I decided I wanted them to also have some practice creating an array from that repeated addition sentence.  So I created this “Creating Arrays” task card set that can be found for free in my TPT store.  16 task cards are included that have the repeated addition sentence on it. Students can then build the array with tiles, cubes, whatever you have and then record their results on their recording sheet.
 
Here’s a peek at it…

Learning About Line Plots

Math, TPT
Last week, we spent the whole week learning about line plots.  This was a new one for me being new to 2nd grade and I loved it! I created all of the lessons we did and tried them out last week in my classroom.  Check all of these out in my new TPT packet – Learning About Line Plots.  On Monday, we started by learning the basics of line plots and only focused on reading a line plot and answering questions from it. 
 
 
 
On Tuesday, we looked at a tally chart, created the line plot from the tally chart, and answered questions. 
 
 
On Wednesday, we completed the whole group project practice in my TPT packet.  Students each measured their shoe to the nearest inch. 

 
 
Then, they wrote down their measurement on a post-it note and stuck it to the board. 
 
 
We then grouped the information together and created a class line plot. 
 
 After creating the line plot, we talked about some different questions and answers using the line plot.
 
 
Then, on Thursday and Friday, we started the line plot project.  Students measured 10 different school supplies to the nearest inch and recorded their results.

 
Next, students created a line plot from their measurement results.
 
And, when they finished their line plots they answered questions using their line plot information.

Check out all of these activities in my Learning About Line Plots packet on TPT. 
Hope everyone is having a great Teacher Appreciation Week!
 
 




March Currently and Measurements Task Cards

Math, Task Cards, TPT

Hard to believe today is the first day of March.  Feels like February flew by.  Here’s hoping the next 63 days of school fly by too.  I’m definitely in spring fever mode and ready for summer!  Since it is March, I’m linking up with Farley for March Currently.  Be sure to link up with Farley at her blog Oh’ Boy 4th Grade.

 
Listening: I’m catching up on my Real Housewives of Beverly Hills on DVR.  Anyone else love watching this drama?  I know these shows are bad for you, but they are pretty entertaining.
 
 
Loving: Wow, what a great sale TPT had.  I know I stocked up on a number of things and am excited to start creating some new products with them.
 
Thinking: I need to start spring cleaning. I don’t want to do spring cleaning, but I need to.  I brought home all of my reading files and am hoping to organize them into binders and clean out the stuff I haven’t used in years.  Here’s hoping I get this project going today.
 
Wanting: More time in the day. I know everyone wants this, but I’ve been feeling pulled lately. I have lots of things I want to get done and good intentions of getting them done then time and other things get in the way.
 
Needing: I have to get back on track with working out. I have good starts and then those taper off. My goal is to get going this weekend and start March off on a good foot.
 
Answer: try to figure out the question that goes along with my answer – Dulce de Leche.
 
 
 
And…I finally have a new product in my TPT store.  I used these Comparing Measurements Task Cards with my kids during our measurement unit and it worked perfectly.  It was hands on, had them measuring actual items in the classroom, and then comparing those measurements.  I also love that student choice is involved. Students got to pick 4 task cards and they could choose which ones they wanted to complete. Here are a few pictures of them working on measurement:

Counting to 1,000 Idea – 2.NBT.3

Common Core, Math

One of the standards in 2nd grade specifically 2.NBT.3 is that students are able to read and write numbers to 1,000.  Now, this seems like a large task and can also seem a bit monotonous.  I didn’t want it to become that way for my kiddos so I came up with a challenge for them. The challenge is they have to take their blank hundreds charts and write the numbers from 1 to 1,000.  Then, when they are finished they get to turn it into a book with a cover that they get to decorate and take home to share with their families. I know this doesn’t sound overly exciting to us since we’re adults – but the kids ate it up!  The other thing I did is limited the time we spent on it each day. If we spent a half hour on it every day the kids would get bored and it would never get finished.  Two to three days a week after we’ve cleaned up math stations we have about 4-5 minutes until we start math. During that time students can work on their counting to 1,000.  Funny enough they even ask to work on it when they have finished their math work early.  Below are a few pictures of my student’s book – he was the first one to finish…

 
Happy Counting!

Addition and Subtraction Strategies

Anchor Charts, Common Core, Math

We spent 2 full weeks working on adding and subtracting double digit numbers with borrowing and regrouping. This is definitely a tough one. Having never taught this in first grade, this was definitely a learning experience for me and for them.  But, on a happy note, my kids aren’t freaked out by it.  I used my CGI (Cognitively Guided Instruction) training from my previous district, we worked on strategies to make it concrete and they’re getting it! 

The three strategies we’re focusing on are….

Place Value – using sticks as the tens and dots as the ones – great strategy for kids who struggle.  Helps them to see it out like the base 10 blocks – great way to take it from manipulatives to no manipulatives.  Below, the student took the nine ones from the top and the one one from the bottom to make a ten – see the arrow.

 
Empty Number Line – starting with the larger number on a empty number line and counting up by 10’s, then 1’s

 
 
 Break Apart Strategy – this one is my favorite – see 2 different ways below of breaking the numbers apart…

 
 
Here are our anchor charts that we made for Adding and Subtracting Double Digit Numbers with borrowing and regrouping – each strategy is listed with an example.  I let students practice all of the strategies then they can pick the one that works best for them.

Adding 4 Numbers – 2.NBT.6

Math, Math Stations, TPT, Why I Teach
 Last week we spent a lot of time practicing adding four numbers. We started with single digit numbers.  Then, we added in some small double digit with the single digit numbers. Then, we went for it – and mixed single and double digit numbers of any size.  The kids did a wonderful job with this and I was so excited to see them using the strategies we had been working on with addition – looking for combos of 10, doubles, place value, empty number line, and break apart. My kiddos that get break apart have taken it and run with it – and I love it! These are the moments that teachers live for – seeing kids take strategies you’ve taught and seeing them apply to it to other situations! I’m so proud of them. 

Anyways, for some of activities that I used with my class – I have created a TPT item in my store – Adding 4 Numbers Activities.  Check it out here…

Adding 4 Numbers - 2.NBT.6
 
 
And, here’s some kiddos working on they’re Roll and Add Game found in my TPT pack above.

And, here’s an example of the Story Problems included…

Comparing Numbers 2.NBT.4 – And a Freebie!

Anchor Charts, Math, TPT

I’ve been meaning to post about this standard and post this freebie for a few weeks, but life got in the way.  So, better late than never…

A few weeks ago we worked on comparing 3 digit numbers – specifically standard 2.NBT.4.  The kiddos did really well with this standard so we only needed a quick few days of practice and they were good to go.  Below are some ideas and pictures from our work…

Here’s our anchor chart we created with vocab, symbols, and a few examples. I love creating these math anchor charts and adding to them throughout the lessons. I find the kids referencing them at later times and love that they are referring to them and using them!

 
 
We then practiced on white boards.  We started with 2 digit numbers and then moved onto 3 digit numbers.

 
I found a ton of great activities from Sunny Days Common Core Essentials Packet – that can be found here.  My kiddos loved playing the Compare and Capture game.
 

And, here’s a little game I created for students to also practice comparing 3 digit numbers.  This game can be found as a freebie in my TPT store…here.
Here are a few pictures from the kids playing…

Double Digit Addition and Subtraction

Anchor Charts, Common Core, Math

My kiddos had struggled a lot with double digit addition and subtraction. Some had learned the straight algorithm, but had no idea what they were doing or why they were doing it, and some were trying to draw 44 circles and 23 circles and then count them all up one by one.  So…I decided we needed some strategies.  We started with straightforward double digit addition and subtraction – no borrowing, no regrouping.  We worked on 3 strategies.  One each day as to not overwhelm students. After exposing them to each strategy and letting them practice each one, they got to choose the strategy that worked best for them.  We worked on place value, empty number line, and break apart.  After we went over these, they really started to get the hang of it and problems weren’t taking 8 hours to solve like the drawing 44 and 23 circles :-).

Here are two anchor charts we made to document our strategies.

 
 
 
 
This week we’ll be tackling regrouping.  I plan to go back to these strategies and also have some fun games that I bought from Amy Lemon’s Double Digit Addition and Subtraction Games pack added in for practice.
 
Hope everyone enjoys the day off!
 

Some Geometry Ideas – 2.G.2

Common Core, Math

Well I had this great post about everything we did the first week back and then the internet went down, it didn’t save, and I lost it.  I was so frustrated the other day that I’m not posting some of those neat activities until now.  I will do better with  my resolution about blogging, but it’ll take a bit to get back into things after the craziness of trying to get back into school mode.

Last week we worked on the Geometry standard – 2.G.2 – where students have to partition/divide rectangles into smaller shapes.

The kids loved the introductory lesson.  I got a packet from The Common Core Creations on TPT called 2.G.2 Activity Pack.   I highly recommend her packet.  On the first day of teaching this standard we did the first lesson called “Cover Up.” Students had a large size rectangle and square and had to cover it up.  Now, the fun part of this and the part all the kids love and will remember is we didn’t use tiles, we used Cheeze-It’s like the packet suggested.  Anytime you give the kids food to work with engagement always seems to occur.  Here are a few pictures of this activity…

 
 
Then, we made a new Geometry vocab book. In this book, we wrote the definitions and drew pictures/examples for the words – row, column, equal, partition, and divide.

Then, later in the week, we did another great activity.  I got this activity from K-5 Teaching Resources (a great website with lots of math lesson ideas and games).  There were 25 different rectangles/squares and I labeled each with a different letter for tracking purposes.  Then, I made my own recording sheet where students could record their results.  Students then picked a rectangle and filled it with tiles.  After filling it, they wrote down the number of rows, columns, and how many tiles total filled their shape.  They had a great time with this activity!

 
 
Hope everyone is having a great week so far! Only 2 more days until a long weekend!

Skip Counting Activities and Stations

Anchor Charts, Common Core, Math, Math Stations, TPT

We’ve spent the past week in my second grade class working on 2.NBT.2.  They are doing a great job skip counting and below are the activities and stations we did to practice.

To introduce skip counting, we spent time with counting collections.  I used pom pom balls, snap cubes, unifix cubes, highlighters, popsicle sticks, straws, etc.  Each item had a different number and was given to the partnership on purpose – to help with differentiation.  Higher kids had numbers in the hundreds – lower kids had numbers in the 40s-80s.  The first direction was just to count and tell me how many the had.  I stopped them about halfway through and we talked about how they were counting.  Most weren’t organizing the items and most were counting by ones, so we discussed was this a good way or is there a better strategy?  I had two groups who had already figured out a strategy.  One group was counting by 10s and another by 20s.  So, we tried this with an example and decided skip counting was easier and it was easier if you grouped them. We went back to the counting collections and now counted while putting them into groups of 2’s, 5’s. and 10’s.

Next, we worked on a skip counting chart to help us.  We colored all of the numbers that were by 2’s yellow, circled all of the numbers by 5’s in orange, and underlined the 10’s in green.  The kids did a great job with this and then had a resource to use throughout the week (especially with the Skip Counting Task Cards (more info on this below)).

 
After making our own skip counting resource, we worked together to create a Skip Counting Anchor Chart.
 
Throughout the week, I introduced the activities below and then on the last day we used each activity at a station.
 
Station #1 –  Skip Counting Task Cards. I created these and have them in my TPT store here.  We used these whole group first and then they were put into a station.  This provides students with multiple chances to practice counting from and to different numbers.  It also goes up to 1,000 and has a few harder cards to provide differentiation.
 
 
Station #2 – School Bus Bump – I found this on TPT here at Lory Even’s store. The kids love bump and now they can play it while practicing skip counting by 10’s.

 
Station #3 – Ordering the Numbers – I found a ton of great skip counting resources on TPT.  Here is a sports one to practice skip counting by ordering the numbers.  This one is from a Series of First Grade Event’s store, which you can access here.

Station #4 – Skip Counting Puzzles.  The kids loved putting these together. I found some cute Home on the Range ones in Haley O’Connor’s store here.

 
Station #5 – Counting Collections – More counting practice with manipulatives – they were told to practice counting the items while grouping them in 2’s, 5’s, and 10’s.
