This number line is an effective way to present numbers and operations in base ten. It is a tool that helps to show modeling and can be kept up all year. The number is written as a word, shown as a number and modeled using base ten blocks.

In this PDF document you have two different visuals. One poster shows the steps to adding two digit numbers, the other poster shows the way to use a hundred chart to add or subtract multiples of ten from a two digit number. There are plenty of review sheet from basic drills to problem solving applications. If you would like contact me and I can provide you with a much larger poster if you want it on display at no extra cost.

This activity can be given to the above level kids that finish early. After teaching that addends produce a sum, you can have kids use the sum to find addends. The workmat is included for those tactile learners.
