Situation Types for Operations in Word Problems
 Description
 Files
The tables below show the 'situation types' or the categories of word problems required by the Standards in which the given numbers and the unknowns are in a variety of configurations. These are excerpted from the progression document, K, Counting and Cardinality; K–5, Operations and Algebraic Thinking.
The first table shows distinct types of addition and subtraction situations: add to, take from, put together/take apart, and compare. Practice with word problems begins simply in kindergarten, but students must leave grade 2 with a strong command of all fifteen situation types within 100.
The second table shows distinct types of multiplication and division situations: equal groups of objects, arrays of objects, and compare. Students begin word problems with these situations in grade 3 and continues through grade 5. Although students initially learn and solve the situation types with whole numbers, this work progresses into word problems involving all rational numbers as well.
