# WORD PROBLEMS with Miss Hutter

## Central Focus :

Students are having difficulties with identifying key words within addition and subtraction word problems which are clues to how they are going to solve the problem. This lesson & learning activities are geared towards students becoming more familiar with these keywords, and using these keywords for creating their own problems.

## Goals/Objectives

• Students will recognize key words within addition and subtraction word problems and use them when creating their own problems
• Students will work in cooperative groups to find keywords and solve selected word problems
• Students will brainstorm ideas with partner and will create 2 word problems for the classroom booklet
• Students will analyze and explain how to solve their two word problems they've created

## Materials:

• Word problem activity guide/computer/polyvision/internet
• word problem cards & scrap paper for groups
• template for creating word problems for booklet

## Assessment:

Informal:

• discussion/ checking for understanding throughout the lesson

• observation of students working with partners on solving practice problems

• observation of students working with their partner to create problems

Formal:

• Student created +/- word problems & how to solve (on back)

## Accommodations & Modifications:

• preselected groups of students to create problems together (adult aid)
• amount of problems to solve/practice & amount made for booklet

## Step 1: Discussion of addition & keywords...

• do addition examples as class, identifying keywords within the problem

• combine

• total
• plus
• sum
• altogether
• in all
• increase
