Moving Up and Down a Hundred Chart by Rows of Ten

Here is where this shows up in real life. A calendar behaves the same way. Down one row is seven days ahead, because each row holds a week. This is worth learning because seeing a pattern makes it far easier to trust and remember.

Watch for it today, and when you spot it, tell someone what you noticed and how you knew. Ask yourself where else the same idea might be hiding, then go and look.

Get your eyes and your fingers ready. The hundred chart shows tens as movement. Moving down one row adds ten. Moving up one row subtracts ten.

Put your finger on 34, move down to 44, down again to 54. Now move up twice and you are back at 34. Because each row holds exactly ten numbers, the chart makes ten more and ten less something you can see with your eyes instead of trusting to memory.

Try tracing the pattern with your finger and saying the numbers out loud: 34, 44, 54. Hearing the ones digit stay the same while the tens climb makes the pattern stick faster than reading about it does. You will use this idea again and again, so build it strong today.
