At the beginning of the year, I use this simple “no fuss” pictorial model activity, to teach my students how to make groups of ten. I put one sheet on the Elmo and model how to start making the groups from left to right. So many images on one page can be overwhelming and confusing for some of them. Especially at the beginning of the year when their little minds are still on summer break!
When they count and circle a group of 10 units, they will see a group of “ten”. The leftover units are “ones”.
Once the students make groups of “tens” they will be able to count them as if they were individual objects. Using these pictorial models helps them determine the sum of a multiple of 10 and one digit number problem up to 99.
You can …
print them out in colored paper
laminate so students can use dry erase markers
make copies and once students complete them, they can paste them in their interactive journals
use them for whole group/small groups or interventions
The images on slides 2-6 are scrambled on purpose to make the students actually count all the individual images one by one. Once they get a group of 10 they circle that amount.
You can differentiate for struggling students by asking them to write the number on the image as they are counting. When they write all 10 numbers they can circle the group to make a “ten”.
The images on slides 7-11 are in row formation for students to recognize instantly the quantity of structured arrangements. They can make their groups of tens horizontally or vertically. Some pages have less than 10 images per rows. Some have more than 10 images to make it more challenging and avoid assuming that each row is automatically a group of “ten’”. (Slide 10 has 10 images per row exactly, let's see if they catch it!)
Once the students have mastered this concept they can compare the different arrangements to see how they can form groups of ten no matter how they are organized!
