How to Use This Pack

Eight lesson plans, one for each lesson of a 3rd grade unit on equivalent and comparing fractions, in teaching order, after an overview page that lays the unit out day by day: a pre-check, the eight lessons, a review and the unit test. Each plan fits on one page. It gives the goal, what to get ready, the words to use, the lesson in five steps with the words to say, questions to ask, common mistakes and what to do about them, and the Animal Math worksheets, tool and quiz for the lesson.

In the Classroom

Print the unit, or just the day's page, and teach from it. Each lesson takes about 45 minutes: a 5 minute warm up, 10 minutes of teaching, 10 minutes together, 15 minutes of practice and an exit ticket at the end. Cut every paper strip from one length, so the wholes always match. The exit tickets and the unit test are separate packs, made for these lessons. Lesson 10.8 (benchmark fractions) is taught in 3rd grade in Virginia; skip it if your state teaches it in another grade.

At Home

Teaching at home? Use the warm up and the "Try it together" step as a short lesson with paper strips folded into halves, fourths and eighths, and the "Words to use" as the way to talk about it. The mistakes to watch for are the ones most children make.

Tips for Success

  • Read the "Watch for" box before the lesson: it is what to listen for while students work
  • Line fraction strips up at the left edge before comparing them
  • Ask "Same top or same bottom?" before every comparison
  • Sort the exit tickets into got it, almost and not yet to plan the next day
  • Use the help and challenge ideas for small groups during practice

Common Core Standards Alignment

This pack supports the following Common Core State Standards for Mathematics:

  • 3.NF.A.2a Mark 1/b on a number line by splitting the space from 0 to 1 into b equal parts; the first part ends at 1/b.
  • 3.NF.A.2b Place a/b on a number line by counting a jumps of size 1/b from 0; where the jumps end is a/b.
  • 3.NF.A.3a Know that two fractions are equal when they cover the same amount of a whole or land at the same spot on a number line.
  • 3.NF.A.3b Find and make simple equal fractions, such as 3/6 = 1/2, and use a picture or model to show why they match.
  • 3.NF.A.3c Show a whole number in fraction form and notice when a fraction names a whole number, such as 2 = 2/1 or 8/4 = 2.
  • 3.NF.A.3d Compare fractions of the same whole that have equal numerators or equal denominators, thinking about part size; record with >, = or < and explain.
  • 4.NF.A.2 Compare fractions with different numerators and denominators using common denominators or numerators, or a benchmark like 1/2; record with >, = or < and explain.
