Eating Our Math Work

We've been learning about different ways to represent and describe 3-digit numbers.  This week we used food to show our thinking about numbers.  The Shreddies represented hundreds (flats), the hickory sticks represented tens (rods) and the Froot Loops represented ones (units).  Our teacher took pictures of us working with the food as we built different numbers.

Later in the week, we got our picture back and then had to write about the number by answering the question "What do you know about the number               ?"  Here is some of our thinking about our numbers.

It has 7 hundreds, 3 tens and 5 ones.

 I stretched the number apart so I did this: 300 + 40 + 5 = 345.

 Six hundred forty-eight is part of the even two pattern.

 200 + 90 + 2 = 292

 In 287, there are 2 hundreds, 8 tens and 7 ones.

 9 is in the hundreds place, the other 9 is in the tens place and the 5 is in the ones place.

 800 + 60 + 5 = 865

 It is in the five pattern and the ten pattern.

 200 + 59 + 1 and 59 + 200 + 1

 It's even and has 3 digits.

 4 X 100 + 7 X 10 + 2 X 2 = 474

 Ten more: 459, 469, 479

 There are 4 hundreds, 4 tens and 9 ones and it equals 449.

 It's spelled: nine hundred thirty-seven.

 1 X 937 = 937

 Ten more is 983 and 10 less is 963.

 100 + 100 + 100 + 100 + 100 + 100 + 100 + 100 + 100 + 10 + 10 + 10 + 10 + 10 + 10 + 10 + 10 + 10 + 1 + 1 + 1 = 993

 I wasn't at school today to do the writing activity.

 It is a 3 digit number.

 I wasn't at school today to do the writing.

 I wasn't at the school today to do the writing.

It's an odd number.

It has eight hundreds.

It is greater than 426.  It is less than 648.
 
I count this number like this: 10, 20, 30, 40, 50, 51, 52, 53, 54, 55, 56, 57, 58.
 

When we were finished all of our hard work building numbers, we got to eat the food--probably the best part of the activity!

We were wondering...

Have you ever used food to help you practice math?
What else can you tell us about our numbers?
