For example: 99 + 493
Add 1 to 99 to equal 100.
Subtract the 1 that you added to 99 from 493 to equal 492.
99 + 1 = 100
100 + 492 = 592
After our regular lesson we had a few extra minutes to play "Tenzi."

Math Today
In today's math lesson we practiced taking apart numbers to help us add. We looked for ways to make a number in the "100's."
For example: 99 + 493
Add 1 to 99 to equal 100.
Subtract the 1 that you added to 99 from 493 to equal 492.
99 + 1 = 100
100 + 492 = 592
After our regular lesson we had a few extra minutes to play "Tenzi."
