I. TOPIC
Learning how to solve problems using multiplication
II. OBJECTIVES/STANDARDS
The students will have a better understanding of how to solve problems using multiplication. The
students will be able to solve multiplication problems using what they learned in class.
Standard - CC.2.2.3.A.1 - Represent and solve problems involving multiplication and division.
III. TEACHING PROCEDURES
Anticipatory Set –
Background – Have four easy multiplication problems on the board for the students to solve.
Have the students solve the problems and see if the students can figure out how to solve the
problems before being taught.
Let them know it will not be grade and to try their best.
Development 1 –
Go over the bell ringer questions and see how the students did. (Most likely the students did not
get them right.)
First – Go over what multiplication means and what the product is
o Multiplication - The process of calculating the product of two or more numbers.
This is a more efficient and easier way to solve addition problems.
Ex: 2 X 5 is better than 2+2+2+2+2
o Product – The answer of the multiplication problem.
What do we call the answers to an addition and subtraction problem?
Addition – Sum
Subtraction – The Difference
Development 2 –
Start teaching how to multiply by two.
o We can use blocks and models to help us solve multiplication problems.
o Start off by showing the students that multiplying by 2 is simply just counting by 2s.
Ex: 2 X 3 = 6
Show them a trick for solving – 2 x 3 would be 2+2+2
Also show them how to solve by drawing circles
Have six circles and draw a circle around 2 of them to make 3 pairs of 2.
Guided Practice 2 -
Get whiteboards out and have students solve 6 multiplications by 2 problems
o Solve one at a time.
o Problems:
2x8
2x4
2x5
6x2
9x2
2x2
o Explain to the students that it does not matter how the problem is set up they equal the
same thing.
Have students solve them using different methods.
o Either counting by 2s or counting with the circles.
Have the students hold up their whiteboards to be checked.
Ask for a volunteer to share and demonstrate on the board how they got the answer.
Development 2 -
Teach how to solve a multiplication problem with 1s and 0s.
o Show the students that when you multiply by one it will always be that number you
plugged in.
Ex: 8x1 = 8
2x1 = 2
o Show them that when you have a 0 in the problem the answer is always 0
3x0 = 0
10x0 = 0
Guided Practice 2 -
Have 6 more problems on the board for students to solve with 1s and 0s
o Have them use whiteboards.
o Check them as a class.
o Problems:
1x3
10x0
1x4
1x7
0x9
1x5
Independent Practice 2 -
Hand out their homework for the night on multiplying by 0,1 and 2s.
Let the students know that the homework is graded on correctness.
Closure –
Ask students what they learned today.
o Have students write down what they learned.
Ask the students what it means to have a product.
o Hopefully they reply with the answer to a multiplication problem.
How do we find the product
o Solve the problem.
IV. Materials
Whiteboards
Whiteboard
Dry erase markers
Worksheet – multiplying by 0,1,2s

V. Adaptions/ Plan Modifications –
For adaptations I will have an extra set of my lesson plan for the day to give to that student to
take home for their parents. This way the parents can know what was taught in class and be able
to help that student with homework.
I'll make sure I am not turned with my back to that student if they have a hearing impairment.
VI. Evaluation –
Formal Assessment – Whiteboards, peer group work
Summative Assessment – Homework worksheet
VII. Reflection –
Did I have enough time and paced out my plan.
Did my students understand everything I taught them or were they confused.
