Unit 02
Energizers (5 min)
Below you will find a new spin on some energizers you may have already used in your classroom. Feel free to continue to use the other energizers listed in Unit 01 by clicking here: http://bit.ly/2evd1Dc.
I love math: Find the sum, how many more to get to 10?
Virtual number dice: single dice, how many more to get to 10?
http://www.curriculumbits.com/prodimages/details/maths/mat0005.htmlI was walking down the street: Use this for combinations to 10.
Example: I was walking down the street and I heard Cynthia say the answer was 10, what could have been the problem?
Opening (5-10 min)
Number Talks with Dot Images: http://bit.ly/2eICQzx
The link above contains dot images. Each dot image number talks consists of three problems, A, B, C. The sequence of problems within a given number talk allows students to apply the strategies from previous problems to subsequent problems. As each problem is shown, ask students, “How many dots do you see? How do you see them?”
Optional Unit 02 Activities
Story Mats and Story Problem Types
Story mats are any type of picture where students can act out the math problem on the mat. Click here for a google slide featuring pictures that could be printed and used with math stories. http://bit.ly/2f0mbnV
While students are using concrete, include also the representational and abstract, even if they still are in the concrete phase to act out the story problem. Keep in mind we don't focus on key words in story problems, but rather the action of what is taking place. For a list of different story problem types click here http://bit.ly/2wE8jax
12 ways to make 11 story and activity
Listen or read the story 12 ways to make 11.
With partners, create a class book patterned off of the story with ____ ways to make 10. You could also make the book into a digital imovie (request a DLC for help!) This also begins the conversation and understanding of the commutative property (the sum remains the same regardless of the order of the addends) and the additive identity property (the sum/difference is not affected when zero is added/subtracted to a number)
The Adding Machine
What you need: plastic solo cups in 2 colors. A box or container for your machine. Some card stock to match your cups, black foam board and a hot glue gun.
To make the machine:
1. Cut the bottoms out of the cups.
2. Glue the cups to the foam board. Put them on the side and angle them IN towards the center.
3. Cut out a plus sign and equals sign. (Just strips of card stock)
4. Glue the symbols on.
Students put 2 number cards in the machine. They place the cards under the cups. They put the correct number of Poms (or other manipulatives) into the cups and they come out in the machine. Then they count the number of Poms and write their equation!
Free number cards and recording charts available here: https://thekindergartensmorgasboard.com/2014/05/kindergarten-smorgasboard-adding.html
The Subtraction Machine
What you need: plastic solo cups, a cardboard box, cardstock
To make the machine:
- Cut a whole in the box big enough for both cups to stack and fit without falling through.
- Cut the bottom out ONE of the cups and stack them.
- Cut out a plus sign and equals sign. (Just strips of card stock)
- Glue the symbols on.
Students put 1 number card in the box. Next place the correct number of manipulatives next to the card. Students draw another card, read the number, and put it in the cup. Students then move that many from the box to the cup. Then they count the number of Poms remaining. Students then draw and write their equation!
Cheez-Frame

Paper Plate Addition/Subtraction
Roll one die. Place that number of buttons in the first section of your plate. Roll the die again. Place that number of buttons in the second section. Add the two sections together and put the correct number of buttons in the bottom half of the plate. Remove the buttons and play again.
Literature Connection:
Animals On Board
Ride along with trucker Jill and her dog as they add up the animals zooming by. But these are no ordinary animals, and they're bound for a surprise destination!
Ride along with trucker Jill and her dog as they add up the animals passing by on other trucks. But these are no ordinary animals, and theyre bound for a surprise destination! Lively illustrations by R.W. Alley make adding truckloads of fun. https://youtu.be/WVKt-ejnFe0Elevator Magic
Equal Shmequal
What does it mean to be equal? Mouse and her friends want to play tug-of-war but they can't figure out how to make teams that are equal. Nothing works until Mouse starts thinking mathematically. Wonderful illustrations capture Mouse and her animal friends from whiskers to tails.

3. Review/Preview:
- Dot Cards: Put this page in a page protector (or front of a binder or laminate), have students use different colored dry erase markers to show the combinations they see. https://drive.google.com/open?id=0B7QrePtgopS0X2o4Q3lxN0EtTlU
(Use this page for an extension: http://www.stevewyborney.com/wp-content/uploads/2016/03/downloadable-massive-space-to-notice-dot-pattern.pdf .) - Clock manipulative exploration
- Build a clock: The next unit will be on telling time. Students can build their own clock before getting to unit 3. This can be an activity they can take home or a velcro activity that can be used repeatedly. Once the clock has been built, students can use linking cubes to show the amount on top of the clock representing the hours. https://docs.google.com/file/d/0B0ZguVRgIEWOYzU5M2ViNzgtYzQyYS00ZmNjLTllZTAtZjQ0MThjYWYzMGQz/edit?hl=en
Fluency:
- I love math: sum then how many more to get to 10? Write a triple part, part, whole
- Salute ( the difference between your number and 10 is _____)
- Make a rekenrek: Instructions found here (cardstock can also work instead of foam): http://www.mathcoachscorner.com/2013/06/diy-rekenreks-take-2/
