Using Frogs for Addition and Subtraction

Here is a strategy I use to engage my students in using a number-line.  

When I first introduce the concept of using a number line as a tool to add and subtract, we pretend that we are frogs and hop forwards and backwards.  We go outside and I tell them to add 1 (they hop forward 1), subtract 3 (they hop backwards 3) etc.  Then we use sidewalk chalk to make number-lines.  After making our number-lines, we act like frogs again and hop forwards and backwards on our chalk-drawn number-lines.  They love this activity.

Now, I have always had the idea in the back of my head to find my own little frogs the students could use in class while they use their number-lines...but no luck....UNTIL, a few months ago while shopping in Walmart for party supplies, I FOUND THEM!  

Use frogs when adding (hopping forward) and subtracting (hopping backwards).  The students will be excited to use their number-lines!
Frogs were purchased from Walmart in the party/goodie bag section.
Number-Lines were purchased from Lakeshore and laminated for durability so students could write with Dry Erase Markers.  (These number-lines were the best thing I EVER purchased!)

We also play a game where all students start their frog on zero and I tell them to add 4 (hop forward), subtract 2 (hop backwards), add 7, subtract 2 etc. The students' goal is for their frog to land on the correct number.  They love this game.  It is great if you have some spare time.

I hope this gets you excited about NUMBER LINES!
