This is a 25 page interactive flipchart with 24 pages of instruction for 1.OA.1: Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing with unknowns in all positions, e.g. by using objects, drawing, and equations with a symbol for the unknown number to represent the problem.
The flipchart starts with 9 different word problems (2 pages per problem). The problems allow students to progress from using objects/virtual manipulatives to solve the problems to a number line and then finally the equation. The first page has the problem using objects and drawings to illustrate the problem. The second page has the same problem with a number line for solving the problem at the top of the page and a place to create the equation at the bottom of the page. The flipchart concludes with 6 additional word problems that are all interactive and include a number line to assist with solving. This contains both addition and subtraction problems.
