Common Core Standards require students to know how to solve many different types of word problems. This 15 page set is aligned with Common Core State Standards to teach Put Together/Take Apart- Total Unknown numbers to 20 story problems. In my experience, students learn how to better solve each story problem type when first taught in isolation. Later, students will know when and how to solve each addition and subtraction situation.
In put together/take apart - total unknown story problems, students solve for the sum or total.
Example: 5 chocolate cakes and 2 white cakes are on the table. What is the sum of all the cakes on the table?
5 (part) + 2 (part) = 7 (whole)
Students are given the opportunity to show their thinking at a higher level by using a variety of ways to solve such as using a ten frame, number line, drawing a model and writing an equation.
