Remember, Understand, Application Write expressions that record operations with numbers and with letters standing for numbers. Evaluate expressions at specific values for their variables
Use variables to represent numbers and write expressions when solving a real-world or mathematical problem; understand that a variable can represent an unknown number, or, depending on the purpose at hand, any number in a specified set
3 types of colored chart paper, scissors, paper and pens

Step1: Cut colored chart paper 6by 6 inches n dimensions and make sets of 3 cards of each color. Also add + – and = signs in that set. (f you don’t have time then you can ask children to make these sets from home. But be specific on the colors you want. every one shud have same set of color cards n class)

Step 2: Distribute the  sets along with the signs to the students n pairs and set the stage for the activity as quiz

Step 3: Begin the class with the following sum on the blackboard:

2+4= ?

3+ ? = 10

Once children have solved the question then begin the quiz using the colored cards

For example: Write on the black board

Green      Blue              Yellow

1. Green + Green = 8
2. Yellow- Blue= 16
3. Yellow -Green= 14
4. What is the value of Green, Yellow and Blue.    Give answers n the order of the color asked .give five mins to solve the questions. in case they are able to solve the question then ask them to explain how they did it.
5. For children who did not get the method you can explain them the process again. You can create more such examples n the classroom and ask children to solve them.
6. Practice sheets with such examples s given n the section below.
