The Importance of Place Value!

What’s Happening

Students are just starting 3 digit addition and subtraction within the classroom! They have mastered 2 digit addition and subtraction with and without regrouping. The next step for them is to make sure they understand the importance of place value, especially when we are working with such big numbers. Students represented a 3-digit number using marshmallows and counted up to that number by grouping their marshmallows in an organized way. This was a great start to 3-digit addition without even realizing it!

“What can I do at home?”

At home, have your child continue to represent numbers with objects around the house. They can start with 2-digit numbers and work their way up to 3-digits. They can use things like rice, Cheerios, paper clips, fruit loops or anything else that is small. Have them organize their objects in groups of 100’s, 10’s, and 1’s to help them count.

What it looks like

Below you will see kids from 1/2- M6 engaged in their marshmallow activity. They are grouping their marshmallows by 10’s and bagging up groups of ten to make it easier to count. They loved doing this hands on math activity and had a lot of fun representing place value with 2 and 3 digit numbers!
