I chose to make an activity with 1.NBT.B.2 which is
- Understand that the two digits of a two-digit number represent amounts of tens and ones. Understand the following as special cases:
- CCSS.Math.Content.1.NBT.B.2a 10 can be thought of as a bundle of ten ones — called a “ten.”
- CCSS.Math.Content.1.NBT.B.2b The numbers from 11 to 19 are composed of a ten and one, two, three, four, five, six, seven, eight, or nine ones.
- CCSS.Math.Content.1.NBT.B.2c The numbers 10, 20, 30, 40, 50, 60, 70, 80, 90 refer to one, two, three, four, five, six, seven, eight, or nine tens (and 0 ones).
I made a product that will go perfect for helping your students understand this concept. It goes hand-in-hand with my Trouble with Monkeys book, but can be used by itself as well. Last week I gave the freebie, but this is the whole pack of 1-100 cards with 4 versions. You get 48 pages of cards...
- 1-100 cards in B&W with numbers
- 1-100 cards in B&W without numbers
- 1-100 cards in color with numbers
- 1-100 cards in color without numbers
With these cards you can do numerous games and activities! It is easy for kids to visualize with oranges instead of the normal manipulative of little blocks and sticks.
Here is a fun activity you can do--Make a secret code.
Simply write a-z on your paper (leaving space for the code number)
Pick blank 1-100 cards and write the number each time you pick one up.
Make messages with your new secret code!
Thanks for visiting! What math concepts are your kids working on? Will you share them with MaTh activity Thursday?
