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

Materials:
Whiteboard
Markers

Small cup filled with 44 beans
Numeral Cards
(Step 3)
Step-by-Step Guided Lesson
Step 1: Start Video
(Tips: Interact with the video by pausing, to ask questions or discuss information viewed with student.)
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.
