Every year the unit on place value, number sense, regrouping (for number sense, not computation) and rounding gives my kiddos such trouble. I need a lot of resources in my aresenal to allow them to work with place value concepts.
This more and less activity where students draw out a card, write the number in the middle column of their recording sheet, and then fill in the more and less column was a great way to accomplish this. It helps students think about how place values change and what happens to numbers when this occurs.
And with adorable ladybugs, perfect little polka dots, and the beautiful bright red color, you can't help but feel cheery while you're doing math!
I like the idea of having those little blanks before more and less so I can decide if I want everyone doing 100 more and 100 less, 10 more and 100 less, or if I want to individualize for each student. If I don't want to use the cards I'll just fill in the center column before running my copies.
The cards can be kept in a plastic baggie or container and set in your math center.
