Lesson+6


 * Adding and Subtracting on the Number Line **

In this lesson, students will use the number line as a tool for solving simple addition and subtraction problems.
 * Objective: **

1. Count forward and backward by 1's from a given number. 2. Model and solve addition and subtraction word problems. 3. Complete number models for addition and subtraction word problems. 4. Use the mathematical symbols +, -, = to complete number models.
 * Key Concepts and Skills: **

Use the following SmartBoard Lesson to aid your instruction.

Students work in pairs or small groups and use pennies to help create and solve their own number stories. Players will take turns telling their own number stories. //Sample story: Jonathan had 7 pennies. He lost 3 pennies. How many pennies does Jonathan have left? // Player Two will use the pennies to model the number story then record the number model using a dry erase board. Both players will work together to check their answers.
 * Differentiation Options: **
 * (+) **

To provide practice using the symbols +, -, = dictate number models for students to record and show on their dry erase slates. //For example: 3+6=9.// The objective here is for students to write symbols to match the words, not to solve the problems.

<span style="color: #1f6cea; font-family: Georgia,serif;">1. Each player needs a number line and a bunny marker. Players take turns rolling a die and moving the bunny the number of spaces shown on the die. <span style="color: #1f6cea; font-family: Georgia,serif;">2. To land on the carrot and bunny hole, students must role the exact number. <span style="color: #1f6cea; font-family: Georgia,serif;">3. The first player to get to the carrot and back to the bunny hole wins.
