Writing basic algebraic expressions word problems

The topic  is a topic under the 6th Grade Math Mission. This exercise practices writing expressions with variables.

Types of Problems
There are two types of problems in this exercise:


 * 1) Use the chart to make an expression: This problem describes a story problem and provides a chart that organizes that information. The student is asked to write an expression to represent the situation described in the chart.Wewvwp1.png
 * 2) Read situation and write an expression: This problem has a situation written, possibly with a minor visual aid. The student is asked to create an expression that models the situation.Wewvwp2.png

Strategies
This exercise is medium to get accuracy badges depending on reading ability. The speed badges are medium because problems repeat at a decent clip, but reading speed will ultimately influence some performance speed.
 * 1) The problems have total needed, money left, and area/volume/folding problems, which correspond to general adding, subtracting, and exponentiation.
