### Speed! - Patterns in the Cards - Six Speed

This is the fifth 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.

Six 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. 6-2-8-4-0.
2. Tens digit is a 0-1-1-2-3 and then a 3-4-4-5-6.

Do you think these patterns would continue if we added more cards? Continue laying out Six Speed cards with the backs up while counting by sixes in your head or writing the numbers on small slips of paper.
66 - 72 - 78 - 84 - 90

The patterns do continue!
Did you find any more patterns? Can you lay your cards out differently and find more patterns?

One thing I found interesting about the sixes is that the one digits are the same as Four Speed, but in reverse order. (4-8-2-6-0 Four Speed) & (6-2-8-4-0 Six Speed). This is more obvious when you do the Waldorf Circle exercise.

- 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 6-2-8-4-0
- If you haven't tried this activity with Four Speed try it now and you should create a star in reverse order.

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