Speed! - Patterns in the Cards - Four Speed

This is the third 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.

Four Speed
Lay your cards out like this. What patterns do you see?
Here are the patterns I found with my son.
1. Ones digit is the same looking down the columns. 4-8-2-6-0.
2. Tens digit is a 0-0-1-1-2 and then a 2-2-3-3-4.


Do you think these patterns would continue if we added more cards? Continue laying out Four Speed cards with the backs up while counting by fours in your head or writing the numbers on small slips of paper.
44 - 48 - 52 - 56 - 60
The patterns do continue!
Did you find any more patterns? Can you lay your cards out differently and find more patterns?

In Waldorf schools kids often use circles when learning their multiplication tables. I like this simple activity because it creates a visual image of a star to go along with Four Speed.

- 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 looking down the columns 4-8-2-6-0


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