Title

Add It Up

Lesson Objective

This activity is designed to teach students to use manipulatives to solve addition problems while recognizing the symbols

of addition and equal value (i.e., add, “and,” plus, +, sum, equals, =, same as).

Background Information for Teacher

This activity should be taught after many hands-on activities, but before you introduce the concept with paper and pencil.

Student Prior Knowledge

N/A

Materials:

● Whiteboard

● Markers

● A bag of small dried beans

● Red and White paint & paintbrush

● Add It Up

worksheet (Step 3)

● Bean Addition

worksheet (Step 3)

● Pencils

● White school glue

● Small cup filled with 44 beans

● Numeral Cards

(Step 3)

Step 2: Teach Lesson

Before you begin this lesson paint 22 beans white and 22 beans red. Allow them to dry before the lesson.

Draw an equal sign and an addition sign on the board and ask the student to identify what each symbol represents and

what they mean.

Write an addition problem on the whiteboard or paper. Tell the the student that they will solve addition problems using 2

different colored counting beans. Give the student a cup with a specific number of 2 different colored counting beans

inside, for example, 4, 5, or 6. The number of beans in the cup depends on the desired sum. Have the student shake their

cup, covering it with their hand, and empty the counting beans onto their desks. Have the student reveal how many "red"

and "white" beans they have.

Pass out Numeral Cards

for the student to use in creating the number sentences that were made using the 2 different

color bean counters.

Demonstrate writing a number sentence with a student’s sample on the Add It Up

worksheet. You may want to make a

copy of the worksheet to complete with the students. This activity demonstrates that changing the order of addends does

not change the sum.

Give each the student the Bean Addition

worksheet and a small cup containing 44 beans. Instruct the student to glue

the correct amount of beans above each numeral and write the answer after the equal symbol.

After the student has completed their sheet, have the student to the board and demonstrate how they solved one of the

problems. The student should write the addition problem and draw the amount of beans that they have represented on

their paper. Then explain how they arrived at their answer and record the sum after the equation.

Step 4: Review. Start the next lesson with the game or activity attached below for review so the student can

demonstrate understanding of this lesson before moving forward.

House Hunt (offline) activity

Have the student find objects such as noodles, cereal, or other objects around the house and add different items. Be sure

to have the student write down their equations in their Math Journal.
