Skip counting by 5s is a little more tricky than skip counting by 10s, just because we have to add an extra count for each 10 we say. However, many students noticed patterns as they wrote their skip counts by 5s. I saw sentences that read, “I see a pattern of 5, 0, 5, 0” (talking about the numbers that are repeated in the ones place). How insightful – especially for only the 2nd week of school! I was delighted with how thoughtful our class responded in their journals to their math work…I’ll have to remember to take some pictures so you can see what I’m talking about 🙂
We created a visual representation as a class that I will hang up to help us remember how to count by 5s (especially after 100!). Each student picked from my “magic pink box of joy” 😉 and received a skip count by 5. They traced their hand, cut it out, and wrote their skip count on the front. We worked together to get from 5 all the way up to 120. Go us!
Skip counting by 5s was a great introduction to a skill that we use often in first grade … using and counting tally marks. To get our brains flowing and thinking in tallies, I introduced the concept with a little “tale”. It goes as follows:
“Five stick friends were walking straight and tall.
The fifth one tripped on a rock and he began to fall!
His friends caught him. He did not touch the ground!
So from now on when you tally, draw the fifth mark lying down!”.
We of course had to illustrate this tally tale, using real sticks and making them into “friends”. We didn’t quite get finished last week, but will continue working over the course of the next few days. Here’s a little preview:)
Hope everyone had a great weekend!
I can’t believe we are starting week 3 tomorrow 🙂
