Speed! - Patterns in the Cards - Five Speed

This is the fourth post in the series of posts. - Speed! Patterns in the Cards - I created the fun card game Speed! to teach multiplication. It uses skip counting to teach children to multiply and how to multiply faster. The series of Patterns in the Cards blog posts are meant to show some simple activities that can aid in number sense development using the Speed! cards.

Five Speed
Counting by fives is usually pretty easy for children. Therefore, introducing Five Speed and the associated patterns can feel like a fun break for the kids.

Lay your cards out like this. What patterns do you see?
Here are the patterns I found with my son.
1. Ones digit alternates between 5 and 0.
2. There are two of each Tens digit except for when it is a 0 at the beginning, and a 5 when the pattern is stopped. - 0, 1,1,2,2,3,3,4,4,5


Do you think these patterns would continue if we added more cards? Continue laying out Five Speed cards with the backs up while counting by fives in your head or writing the numbers on small slips of paper.
55 - 60 - 65 - 70 - 75
The patterns do continue!
Did you find any more patterns? Can you lay your cards out differently and find more patterns? Try laying them in two columns.

Try counting by fives while doing the Waldorf circle activity from last week.

- draw a circle
- place 10 evenly spaced dots around the perimeter of the circle
- label the dots 0 thru 9
- starting at 0 draw lines in the order of the ones digit counting by fives (5,0,5,0,5,0,5......)

The result should be a circle with a vertical line.


When you are done with this activity get out Six Speed and get ready for next week.
