Counting by Fives

Remember last week we learned how to count by tens? If you missed the post you can see it here. After this excercise I caught Selena counting 5, 10, 520, (five twenty) so on up to one hundred. I went to my bin of bottle caps and had enough blue caps to make the numbers 1 – 9 and an extra five.

100_4508 We started out by refreshing our memory on how to count by tens. Which Selena hadn’t forgotten one bit, she went right through counting by tens like she had been doing it forever.

100_4509 We then added the blue bottle caps, so our number line looked like 1,1,2,2,3,3, so on to 100. I placed the extra 5 at the top of the line, and the 0 next to the one so we had our start 5, 10. I then showed Selena how she could move the 5 to make 15 and then move the 0 to make 20. It took her a few times of trying this new concept, but she caught on quicker then I thought she would.

100_4515 She practiced this for about another 30  minutes, and is now pretty confident in herself that she can count by not only tens but now fives as well.

  1. There are so many wonderful things you can do with lids.

    I need to start saving them again.

  2. Very neat way to help Selena see the pattern! You are a great teacher.

  3. I love this idea. I must have missed your post about counting by 10s last week, but I just love how you're using the lids for this. I'm definitely going to start saving lids so we can do something similar.

  4. I really like the way you did this. Very clever! It definitely worked for Selena!

  5. I need to get collect bottle caps! :)
