Letter to Family

Dear Family,

I would like you to do something with your child that involves preparing food

and subtraction. I would like you to start with 12 to 18 of an ingredient and then

use 9 or less of that ingredient for what you are preparing. Then I would like

you and your child to figure out how many of that ingredient you did not use.

For example, you might be making a salad. You start with 15 tomatoes and

use 7 of them in the salad. So you have 8 tomatoes left. I would like your child

to make a picture of what you did and to write the subtraction sentence.

In class I will put the children in pairs, and each child will share his or her

drawing with another child.

Your child needs to bring this to school by

(date)

Thank you for your help.

Sincerely,
