Unit Overview

This is a five day (7.5 hour) unit on solving multistep word problems. The topic of the instructional unit is the standard MGSE4.OA.3. This 4th grade standard requires students to solve multistep word problems using whole numbers using the four operations. Students should also be able to interpret remainders and represent problems using equations with symbols standing for unknown quantities. This standard is extremely important to students’ overall success throughout the year as well as when students take part in standardized testing at the end of the grade.  The intended audience is 4th grade regular education students in a mathematics class.

Instructional Goal

The 4th grade regular education students will be able to master GA standard M4OA3a, multi-step word problems. The students should be able to apply CUBES to break down word problems into smaller steps and identify the operation to be used during summative assessment in google classroom with 80%.

Performance Objectives

Lesson 1 Performance Objective: Given three multistep word problems, students will solve the problem correctly 100 % of the time in 3 out of 5 opportunities.

Lesson 2 Performance Objective:  Given three numberless word problems, students will solve with 100% accuracy in 3 out of 5 opportunities.

Lesson 3 Performance Objective: Given three multistep word problems, students will solve with 100% accuracy in 3 out of 5 opportunities.

Lesson 4 Performance Objective: Given five multistep word problems, students will solve with 100% accuracy in 4 out of 5 opportunities.

Lesson 5 Performance Objective: Given 10 multistep word problems, students will solve with 80% accuracy in 1 out of 2 opportunities.

Delivery Approach

Whole group instruction, independent practice, frequent formative assessment, and small group learning that includes teacher/intervention are used throughout the unit with the activities culminating into a summative assessment on day 5. Cognitive learning will be used to build on understanding from previous learning. Students will have already mastered one and two-step problems. By using CUBES, we will focus on the mental process to identify steps to take to break down essential information to effectively solve the multistep word problems. Students will link prior learned concepts, be provided structure to solve real world problems. CUBES (see anchor chart below) is a mnemonic for the steps of solving multistep word problems. Students will also learn in cooperative learning groups of mixed ability. This falls within the constructivism learning theory. This is applied through problem based learning and collaborative/group work. The behaviorist learning theory is also used throughout the plan because students are given instant feedback from the teacher to elicit the desired correct response.
