This product is the Level 2A Problem Solving Notebook. The numbers in the word problems in the Level 2A notebook are from 0-20, making this great to use from the very beginning of the year on. The Level 2B workbook will be released later in the year and will use 2-digit and 3-digit numbers with each problem type and introduce basic multiplication and division. The Level 2A workbook gives students an opportunity to master problem solving skills and drawing strip diagrams while still using smaller numbers. The cognitive demand of using large numbers with challenging problems can be overwhelming for many students.

The detailed Teacher’s Edition for the Problem Solving Notebook is 63 pages long and includes many tips for teaching word problems. The TE explains each problem type and how the strip diagram is best used to support students for each type of problem.

The Student Problem Solving Notebook includes 197 word problems organized into 5 sections: Join Problems, Separate Problems, Part-Part-Whole Problems, Compare Problems and Mixed Problems. Each section introduces a new problem type with instructional pages. The introduction pages also go through all possible placements for the unknown in the problem. The Mixed Problems sections includes all 4 types of problems.
