Monday Math Freebie - More or Less "I Have, Who Has?" Cards

Classroom Freebies Manic Monday
My class is studying number sense and place value right now. To get them thinking about what this looks like I created a set of "I Have, Who Has?" cards for working on understanding tens and ones, as well as what happens when you add tens or ones to a number.

Included in this file you’ll find 4 different sets of “I Have, Who Has?” Cards for working on the following concepts:
  • one more/one less
  • two more/two less
  • ten more/ten less 
Each set contains 24 cards. You’ll find the following formats on the card sets:
  • Base-10 blocks
  • Tally marks
  • Expanded notation
  • Standard form
Here's what they look like.
These cards were designed to meet the following Common Core Standards for Math:
  • 1.NBT.2 - Understand that the two digits of a two-digit number represent amounts of tens and ones. 
  • 1.NBT.4 - Add within 100, including adding a two-digit number and a one-digit number, and adding a two-digit number and a multiple of 10.
  • 1.NBT.5 - Given a two-digit number, mentally find 10 more or 10 less than the number, without having to count; explain the reasoning used.


I hope you get a chance to use this in your home or classroom. Please let me know if you try this and how your kids like it.
