TeachTransform’s 3rd Grade Perimeter, Area, and Time is all about understanding units of measurement to solve problems. Students model the figures and use their models to choose area or perimeter. Activities include scaffolding so measurement is accessible for all students. 

Centers and hands-on activities keep students interested and develop problem solving grit. For example, students create a robot to practice composite area and solve time problems with Lucy Dynamic and her friend Carl.

3rd Grade Perimeter, Area, and Time includes activities for the whole class, small groups, centers, intervention, and guided math that build the academic language of measurement.

Each activity includes:

  • TEKS
  • Setting Up for Instruction
  • How-To Guide with full teacher directions including questions
  • Thought Extender Questions to help students get ‘unstuck’ and focus on the math concepts
  • Answer Key
  • Content explanations to deepen teacher understanding of fraction concepts
  • Instruction extras to support implementation of instructional strategies

Tutoring & Intervention

3rd Grade Perimeter, Area, and Time activities can be used for Tier 1, Tier 2, and Tier 3 instruction in 3rd grade. The activities can also be used to catch 4th and 5th graders up and fill in gaps without loss of rigor or time. For example, for 4th graders struggling to understand the difference between perimeter and area, use Mia Measures Up or Cover or Go Around? from 3rd Grade Perimeter, Area, and Time. For 4th graders struggling with time problems, use Zappo the Great or Springback Jack’s Scheme.

Instructional Alignment from Grades 3–8

TeachTransform’s measurement books are tightly aligned from elementary through Grade 8 in both instructional style and modeling, providing students a seamless transition from an elementary concrete approach to measurement to an algebraic, middle school approach.

For students who are “growing up” with TeachTransform’s instructional materials, you can expect them, with a little prompting, to give an answer that includes a why, to use sentences to explain their thinking, to question each other in small groups. This lightens the instructional and cognitive load in each grade and leads to mastery.
