Note from the author:
Develop Understanding
Today's Learning Goal (G3, U1, L13):
  • Relate equations to multiplication situations and diagrams.
  • Write equations for multiplication situations and diagrams using a symbol for the unknown number.
Today's Materials:
  • Laptop
  • Laptop charger
  • Pen/Pencil/Paper (optional)
Please complete the Jump Start (activator). You have 5 minutes before we review. This is independent it should be silent.
Reminders:
1. Ready for class
2. No cellphones
3. Volume must be low.
4. Read and follow all directions
5.) Take your bag off and immediately begin the Activator.

Jump Start Activator- (3-5 minutes)


In your groups, Pick one that doesn’t belong. Be ready to share why it doesn’t belong.

Launch: Which one doesn't belong? - (5-10 minutes)

How is part (C.) different from the other parts (A.,B.D.). Talk in groups!

Explore A1: Multpication Equation Match - (15-20 min)

In groups 2-4 match an equation that represents each situation and diagram. Keep in mind What parts of the situation, drawing, or diagram were especially helpful as you write out the equation. I'll model (A.) and we will do (B.)
Required
1

Complete A. - I. Find an equation from the list that can represent each situation, diagram, or drawing. Record the equation. Be prepared to explain your reasoning.

Explore A2: Write Multpication Equation Match - (15-20 min)

In groups write an equation that represents each situation and diagram. I'll model (A.) and we will do (B.)
Required
1

Write an equation that represents each situation, drawing, or diagram. Be prepared to explain your reasoning.

LESSON SYNTHESIS - (5-10 min)

1

Expression: 3 x 5

Equation: 3 x 5 =15

Today we learned about equations and how we can use them to represent multiplication. In this equation, 3 and 5 are the factors and 15 is the product.
  • How are multiplication expressions and equations alike?
  • How are multiplication expressions and equations different?
  • When would each be helpful?
Talk in groups

Cool Down - (5 min)

Required
1

Select all the drawings, diagrams, and situations that could represent the equation.

KHAN ACADEMY FOR 30 min!!

Closure Questions:

  • What kind of ways can you represent a multiplication equation?
  • What makes a multiplication equation an equation?
  • 4 x 5 =20
what are 4 & 5 called? and what is 20 called? in the equation above.
