Make the picture below with three turtles. Use the same size shapes as you used in the other tangrams.
Simple MadLib.
number: 3
cost each: 2.95
plural noun: tomato plants
If I have 3 tomato plants and clone them all, then I have 6, costing $17.70 total.
Of course make it so that you can type different numbers and nouns.
You should have the measurements of the tangram pieces in your notes. Use my diagram if you need it.
