Hundreds chart and calculator applet!

Something I wanted to mention especially for my friends at early primary is this National Council of Teachers of Mathematics site. It’s a hundreds chart and a calculator applet – as you punch numbers and add to them, the corresponding numbers in the hundred’s chart are highlighted. it’s pretty cool – and very visual, which of course we all like…

Click here for the Hundreds Chart and Calculator applet.

Encourage your students to record their number patterns on the hundreds chart, then take a screen capture and print off their unique pattern.  Afterwards they can include a sentence describing their pattern rule.

it looks like this:

My pattern rule was fairly simple. Start at 2.  Add 2 each time.

Hm.  I wonder if I will hit 37? 54? 100??
