Your students will have so many ways to master sums of ten using both two addends and three addends when they use the activities in this set of dinosaur themed math cards.

Here's what's included in this set of activities for two addends and three addends!

* 30 Dinos at School number cards. Each card has four numbers on it. Students will determine whether any combination of two or three addends totals ten.

* Read the Room and Scoot (recording sheets and answer key provided)

* A board game

* A sort and graph activity

* Task cards to explain these and other activities

The activities in this set can be differentiated: find two addends that have a sum of ten, or find either two or three addends that total ten.

How can you use these addition activities with your class?

* Play Scoot with your whole class! Just make a "trail" of the cards around your classroom. Give each student a clipboard and a recording page. Position your students along the trail, with each one at a card. Allow a few moments for solving the cards and writing the answers, and then give a signal for everyone to move to the next position on the trail, continuing until all students have visited each spot.

* Similar to Scoot, Read the Room will also get your students up and moving! You can use Read the Room form to use this as a whole group or math center activity.

* Use the 30 sums of ten number cards for sorting activities (directions cards included!) in math centers or in small groups.

* Graph the results of your sort.

* Use the easy-prep one page game in your math centers or math tubs.

to see state-specific standards (only available in the US).
Decompose numbers less than or equal to 10 into pairs in more than one way, e.g., by using objects or drawings, and record each decomposition by a drawing or equation (e.g., 5 = 2 + 3 and 5 = 4 + 1).
Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 - 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
Organize, represent, and interpret data with up to three categories; ask and answer questions about the total number of data points, how many in each category, and how many more or less are in one category than in another.
