Super Granny was flying 16 yards above the ground when she heard a cat meowing. She flew another 20 yards up to reach the cat. How many yards did Super Granny fly altogether?
___ + ___ = ___
16 + 20 = ___
Let’s find the sum of 16 + 20 using a number line. First, place a dot above the larger addend on the number line.
16 + 20 = ___
16 + 20 = ___
What digits make up the smaller addend?
16 + 20 = ___
16 + 20 = ___
1 tens 6 ones
16 is made up of 1 ten and 6 ones. In order to add 16, we can jump to the right by ten one time. Then, we can jump by one 6 times.
16 + 20 = ___
1 tens 6 ones
16 + 20 = ___
1 tens 6 ones
The number the last jump lands on is the sum.
16 + 20 = 36
1 tens 6 ones
Super Granny flew a total of 36 yards to reach the cat!
Super Granny flew 30 feet to a tree. Then, she flew another 29 feet to a bird. How many feet did Super Granny fly altogether?
We should begin at 30 because it is the larger addend. Then, we jump 2 tens and 9 ones to the right. The sum is 59.
Yes! We begin at 30 because it is the larger addend. Then, we jump 2 tens and 9 ones to the right. The sum is 59.
We should begin at 30 because it is the larger addend. Then, we jump 2 tens and 9 ones to the right. The sum is 59.
