Lesson 5
Use the clue and the grid to figure out which pile of laundry each child
folded.
Clue: The pieces in Daniel’s pile were not square.
1. Look at the grid below. Daniel and Carrie were folding laundry. Daniel’s pile
did not have squares, so it was not a washcloth. An X has been placed in
the box that stands for the washcloths under Daniel’s name. Daniel folded
the socks. Put a dot in the box that stands for socks under Daniel’s name.
Now we know that Carrie did not fold the socks, because Daniel did. Put an
X for the socks under Carrie’s name. Carrie folded the washcloths. Put a
dot in the box beside washcloths that stands for Carrie’s name.
Daniel Carrie

Answer
Daniel

Now you try one.
2. Rhoda and Daniel each have a pet. Use the grid clue
to find each child’s pet.
Clue: Rhoda’s pet does not have long ears.
Put an X in the boxes that can’t be true. Put dots in the boxes that are true.
Rhoda Daniel

Looking for Addends that Equal 10
4 + 5 = 9...9 + 6 = 15...15 + 7 = 22...
22 + 3 = 25...25 + 1 = 26
Daniel solved this problem by adding the
addends in the order they are given.

Carolyn, another third grader, found an easier way to solve this problem.
First she looked for addends that equal 10 and crossed them out. She found
2 tens. Then she added the numbers that were left.
4 + 6 = 10, 7 + 3 = 10
Two tens equal 20.
5 and 1 are left.
5 + 1 = 6, 20 + 6 = 26
