Class:Math

Date:11/24/12

Standards: MACC.1.OA.1.1: 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, drawings, and equations with a symbol for the unknown number to represent the problem.

Content Objective:

The students will use manipulative to solve addition and subtraction word problems with 85% accuracy.

Language Objective:

The students will discuss the word problems with their peers to determine the important information that they need to solve each math word problem.

Key Vocabulary:

Addition, Subtraction, altogether, less, equals

Materials: (supplementary and adapted)

Document Camera, Vocabulary poster, Solar System Math Worksheet (class set), pencil, two-color counters.

High-Order Questions:

1. When working on answering a word problem, how do I know if I need to add or subtract?

2. After reading a word problem, what would be the next step I should take to answer the question?

Time:

5 minutes

15 minutes

Activities:

Building Background:To build upon the students background knowledge the teacher will begin by reviewing addition problems with the students. The teacher will then ask the students a very basic word problem and model how to solve it. When modeling how to solve the word problem she will underline key words that help her to determine key information. The teacher will also model how to use color counters to solve the equation.

Links to ExperienceThe teacher will then complete 2+ word problems as guided practice with the students. She will use informal assessment of a show of thumbs to determine if additional guided practice is needed. The teacher will then allow a few student volunteers to come up, one at a time to “be the teacher” and explain and demonstrate the process of solving word problems.

15 – 20minutes

Links to Learning:Students will then work with their predetermine math partners to complete the Solar System Math Worksheet. The students will need to underline the key terms necessary to complete the problem. The students will also have the two-colored counters to help them if needed.

Key vocabulary:

Addition, Subtraction, altogether, less, equals

Student Activities (Highlight activities applied in this lesson)

Scaffolding: Modeling Guided Independent

Grouping: Whole Class Small Group Partners Independent

Process: Reading Writing Listening Speaking

Strategies: Hands-On Meaningful Links to Objectives

Time:

5 – 10 minutes

Review and AssessmentIndividual Group Written Oral- The students will be informally assessed during the discussion

for proper use of key vocabulary.- The students will be assessed on the completion of their Solar

System Math Worksheet

Review Key Vocabulary:

While the students are completing the worksheet, the teacher will be listening for the students using the key terminology while discussing the word problems with their peers.

Review Key Content Concepts:

After the students have completed the worksheets the students will go back to their seats and the students will guide will explain to the teacher how they answered the word problems while the teacher demonstrates the steps and solution on the document camera.

Extensions: The students will use their new vocabulary and underlining important information strategy for future word problem lessons.. The word problems are also made from true facts about the Solar System, so it can also serve as a Solar System review.
