MA.3.FR.2.2

Identify equivalent fractions and explain why they are equivalent.

Examples

Example: The fractions begin mathsize 12px style 1 over 1 end style and begin mathsize 12px style 3 over 3 end style can be identified as equivalent using number lines.

Example: The fractions begin mathsize 12px style 2 over 4 end style and begin mathsize 12px style 2 over 6 end style can be identified as not equivalent using a visual model.

Clarifications

Clarification 1: Instruction includes identifying equivalent fractions and explaining why they are equivalent using manipulatives, drawings, and number lines.

Clarification 2: Within this benchmark, the expectation is not to generate equivalent fractions. 

Clarification 3: Fractions are limited to fractions less than or equal to one with denominators of 2, 3, 4, 5, 6, 8, 10 and 12. Number lines must be given and scaled appropriately.

Lesson 22 Video: MEA Animal Meal Planning Part 2:

In this video, SaM-1 introduces a part 2 twist to the Model Eliciting Activity (MEA). In the optional twist, students will need to modify their original diet for a senior chimpanzee. The first video provided meal planning information to add to the knowledge students gained throughout the unit to start the challenge.

In this video, SaM-1 introduces a Model Eliciting Activity (MEA) challenge for the students. This video provides meal planning information to add to the knowledge students gained throughout the unit. Students will be asked to develop a varied diet for a chimpanzee at the CPALMS Rehabilitation and Conservation Center based on the color, shape, texture, and hardness of the food.

In the optional twist, students will need to modify their original diet for a senior chimpanzee. The optional twist also has a SaM-1 video to introduce the twist challenge.
