This download includes a month’s worth of problem-solving questions for second grade. It is aligned to the second grade common core standards, but can be used for third or fourth grade for struggling students.
This packet uses addition and subtraction of money with and without regrouping.
We use number bonds and bar models as part of our curriculum so that is the strategy being used in this packet. The first 2 weeks are number bonds focusing on part-part-whole, and the second 2 weeks are all bar models. There is a detailed answer key to all student sheets and assessments.
The preview file contains only a few of the sheets in the full file.
In this download you will get:
2 page lesson overview with goals and Marzano strategy
1 page steps to following bar models
27 student pages including 4 end of week assessments for data points
32 page detailed answer key

* Incorporate words and images using symbols to represent relationships.

CC.2.OA.1 Use addition and subtraction within 100 to solve one- and two-step word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem.
CC.2.OA.2 Fluently add and subtract within 20 using mental strategies. By end of Grade 2, know from memory all sums of two one-digit numbers.
2.NBT.7. Add and subtract within 1000, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method. Understand that in adding or subtracting three-digit numbers, one adds or subtracts hundreds and hundreds, tens and tens, ones and ones; and sometimes it is necessary to compose or decompose tens or hundreds.
