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

Welcome to the second week of 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.

Three Speed
Lay your cards out like this. What patterns do you see?

1. Read only the ones digit on each card. Can you find a pattern when you count 1, 2, 3, 4, 5, 6, 7, 8, 9 using the ones digit? - left-hand column going from bottom to top, middle column going from bottom to top, right-hand column going from bottom to top

2. Read only the 10's digit. Top row - 0, 0, 0; Middle row - 1, 1, 1; Bottom row - 2, 2, 2 then a 3

3. Can you see the numbers in Six Speed! within Three Speed? 6, 12, 18, 24 - When you touch them in this order do you see their pattern?

4. Can you see the numbers in Nine Speed! within Three Speed!? 9, 18, 27 - When you touch them in this order do you see their pattern?

Do you think these patterns would continue if we added more cards?

They do.
Did you find any more patterns? Can you lay your cards out differently and find more patterns? When you are done with this activity get out Four Speed and get ready for next week.
