Can you find 10 ways to make 100?

Show 10 ways to make 100 using addition. Write your equations below.  For every equation we are adding with the ten with the answer we have got
in the previous sum.

Turn and Talk

Share your equations with a partner. How are they alike and how are they different? Explain why you might use numbers with a 0 in the ones place.
15 + 5 = 20
10 + 10 = 20
Explanation:
the sum of the both equations are same but the inputs given was
different.
the inputs may be different
we have to get the sum same
alike, 17 + 3 = 20

How does it help to find sums of 100 if you know sums of 10?
if we add zero for the sums of ten then
it will be same for 100
15 + 5 = 20
150 + 50 = 200
We have to add extra zero in the ones place Complete these problems to review prior concepts and skills you will need for this module.
