Reflection: Recalling Prior Knowledge of Adding and Subtracting Fractions - Section 5: Work It Out

 

While teaching this lesson you might realize, as I did, that my students need a lot more work on equivalent fractions. This became a two day lesson.

I also like to challenge those higher learning students to test their ideas (very Common Core). Take this lesson slow and check often for understanding, their whole fraction lives depend on this work! Don't get discouraged and know that fractions are a really hard concept for 5th graders.

Recalling Prior Knowledge of Adding and Subtracting Fractions

Unit 2: Adding and Subtracting Fractions with Unlike Denominators
Lesson 1 of 7

Objective: Students will be able to add and subtract fractions by using common denominators and equivalent fractions.

Big Idea: The denominator represents the WHOLE and the numerator represents the BITS/PIECES so in order to add fractions we need to have the same denominator.
