Reflection: Diverse Entry Points The Video Game Model of Adding - Section 2: Guided Practice


When adding on from 1,100 to get to 2000, using increments of 100, this child creates the equation 1,100 + 3 (3x100) = 2000. A simple visual enabled him to make that leap, which was an unintended consequence of the lesson.

The Video Game Model of Adding

Unit 3: Multiplication
Lesson 11 of 11

Objective: SWBAT create and verbally explain and demonstrate, with models and equations, multiple ways to add on from a given number to 2000 using repeated addition of 50 and 100 and multiplication of 50 and 100.

Big Idea: Video games often dole out points in groups of 25, 50 and 100 because they are easy numbers to multiply. Practice with patterns of 5 and 10 apply directly to understanding patterns with 50 and 100.
