Elimination: multiplying before adding
Content is AI-assisted and continuously improved through educator review
Learning Objective
Students will explore elimination and multiplying before adding through guided practice and application.
In this lesson, we'll explore elimination: multiplying before adding. Mathematical thinking develops logical reasoning and problem-solving abilities.
Addition means putting groups together to find the total. When we see 3 + 2, we start with 3 objects and add 2 more. We can count them all to find the answer: 1, 2, 3... then 4, 5. So 3 + 2 = 5. The "+" symbol means "plus" or "add," and the "=" symbol means "equals" or "the same as."
As you work through today's material, pay attention to the examples and try to identify the patterns or strategies being used. This will help you apply these concepts to new problems.
Take notes on key points and make connections to what you've already learned in previous lessons.
