Grid Multiplication Model:

Multiplication Facts

• As math gets more challenging, kids need to make sure they know their math facts or they won't be able to move on.
• Kids can't go back in mathematics
• There is forced progression in math, THEY NEED TO KNOW THEIR MULTIPLICATION FACTS

Multiplication Fact Strategies

• 9 = 10 take away 1 
• 9 x 4 = 10 x 4 = 40 then take away one group of 4 40 - 4 = 36
• 2 = double
• 4 x 2 = (4 + 4 = 8)
• 3 = skip counting
• 4 = double, double
• 4 x4 = (4 +4 +4 +4 = 8 + 8 = 16)
• 5 = skip counting, there is a pattern
• 6 = 5 plus 1
• 6 x 5 = (5 x5 = 25 + 5 = 30)
• 7 = skip counting
• 8 = double, double, double
• 12 = ten plus 2s 
• 12 x 2 = (10 x 2 = 20 +2 + 2 = 24)

Lesson Study

• Launch - how are you going to prep those kids for the lesson
• What are the guiding questions?  Get the students talking.
• Anticipatory set - where students may make mistakes
• Interventions - how can you respond to the student errors
• Exploration
• What are the guided questions
• Anticipatory set
• Interventions
• Wrap Up/Classroom Discussion
• What are the guided questions
• Anticipatory set
• Interventions
• Assessment Piece
