BIG IDEAS
ESSENTIAL QUESTIONS / DO
Introduction/Anticipatory Set/Instructional Input/Modeling:
· Lesson Review 4-5
· Ask about students’ favorite sports. Ask about favorite players on teams.
Learning Experiences:
Introduction 4-6
· Show YouTube clip of basketball game (load ahead of time and click halfway through to show the actual game highlights
· https://www.youtube.com/watch?v=P1pDvlVjebM (googled ny knicks vs la lakers)
· Discuss with students they will explore a basketball scenario between La Lakers and NY Knicks. Provide the following:
There are 12 players on each of the NBA basketball teams. There are 29 NBA basketball teams in the United States. How many players are on all of the teams in the NBA?
· Allow students to explore this for a moment, then discuss.
· Guide students through solving this problem in both the area model and the distributive model (see below)
· Share with students that by the end of today, they should be able to use the distributive property of multiplication to solve two-digit multiplication problems.
· Use EnVision Math Online “Use the Distributive Property to Muiltiply” to further explore the Lakers vs Knicks problem using the distributive property of multiplication.
· Develop Problem-Based Learning: Solve and Share
· Develop Visual Learning: Visual Learning Bridge, Visual Learning Animation Plus, Convince Me! Guided and Independent Practice, Practice Buddy – Independent Practices and Problem Solving
· Check work to differentiate.
Grouping (Whole Group, Small Group (Readiness, Interest , Learning Profile), Individual):
Per lesson, use leveled practice pages (re-teaching, on-level, enrichment) reaching all learners activities, leveled practice options, or early finisher activities
Closure:
· Revisit initial basketball math problem, and others like it. Use an exit card to have students demonstrate their learning through solving another problem like it. They must explain how they solved it. Results will be used to differentiate leveled homework.
· As an extra practice for math fluency:
o Show Flowcabulary multiplication factshttps://www.flocabulary.com/topics/multiplication-division/
o Show Math Tricks : https://www.youtube.com/watch?v=auIfxnX0rjc
Resources/Materials:
· Overhead projector and elmo
· EnVision math online resources
· Student handout
· Student textbook
· Exit Cards with one math problem on it
· Leveled homework
Post-Assessment:
· Leveled Homework and Practice, or online “Buddy Practice.”

See below for actual order of activities for lesson.
There are 12 players on each of the NBA basketball teams. There are 29 NBA basketball teams in the United States. How many players are on all of the teams in the NBA? Use the area model below to solve.
20 / 910

There are 12 players on each of the NBA basketball teams. There are 29 NBA basketball teams in the United States. How many players are on all of the teams in the NBA?
20 / 910 / 200 / 90 / 290
2 / 40 / 18 / 58
348
Here is what the Distributive Property solution would look like for 12 x 29 =
= (10 + 2) x (20 + 9)
= (10 + 2) x 20 + (10 + 2) x 9
= (10 x 20) + (2 x 20) + (10 x 9) + (2 x 9)
= ______+ ______+ ______+ ______
= 200 + 40 + 90 + 18
= 348
Solve this problem using the area model and the Distributive Property:
There are 82 games in one NBA season.
If Kobe Bryant averaged 34 points per game, how many points would he have scored in one season?
