Math Task Monday Math: Operations and Algebraic Thinking 2. Solve word problems that call for addition of three whole numbers whose sum is less than or equal to 20, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem. Teacher note: Start with 10 counters in a cup. Then, follow the script.

What’s Hiding? I have some counters in my cup. I take out 3. 7 are left. How many counters were in my cup? Write a number sentence to represent the problem. Use “c” to represent the missing counters.

One more together _____ = 5-5 How many counters are we starting with?

One more together _____ = 5-5 5! How many are we taking away? 5!

One more together _____ = 5-5 5! How many are we taking away? 5! How many are left?

One more together ___0__ = 5-5 5! How many are we taking away? 5! How many are left? 0!

Try with your partner on your white board. ___-0=______ (Call on volunteer to explain their thinking)

Try with your partner on your white board. _2__-0=___2___ (Call on volunteer to explain their thinking)

Try one on your own. _____ - 0 = _____ Write it and hide it.

Try one on your own. Count carefully. _____ - 0 = _____ Ready, set……Chin it!

Try one on your own. Count carefully. __6___ - 0 = __6___

Try one more on your own. Count carefully. _____ - ______ = 0 Write it and hide it!

Try one more on your own. Count carefully. _____ - ______ = 0 Ready, set….Chin it!

Try one more on your own. Count carefully. __6___ - __6____ = 0 Ready, set….Chin it!
