Hi there! It's Michelle from Apples and ABC's, and I want to share an idea about how to introduce and teach counting with base 10 blocks to your students. My goal this year in math is to do a better job at teaching and creating opportunities to count with base ten blocks. Our curriculum is just starting to cover numbers 11-20 so it's time to bring out the blocks to start counting!
Here is a simple way to get your students comfortable with counting and writing numbers 11-20. I did this activity as a whole group and used my projector and ELMO to show the students how to count and write the numbers. I would place the number of blocks under the projector, and the students had to write that number on their whiteboard.
When I rang the bell, that meant erase the whiteboard and get ready for me to place the next set of blocks under the projector. Again, we would count the blocks as a group and everyone would write down the number.
Once we practiced this several times as a whole group, I gave the students their own blocks to use. They placed blocks on their whiteboard and then wrote the number. This was such a simple, engaging activity for all of my students!
CCSS.Math.Content.K.NBT.A.1 Compose and decompose numbers from 11 to 19 into ten ones and some further ones, e.g., by using objects or drawings, and record each composition or decomposition by a drawing or equation (such as 18 = 10 + 8); understand that these numbers are composed of ten
ones and one, two, three, four, five, six, seven, eight, or nine ones.
