How to Use This Pack

Eleven lesson plans, one for each lesson of a 3rd grade unit on perimeter and shapes, in teaching order, after an overview page that lays the unit out day by day: a pre-check, the eleven 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, makers, tools 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. The exit tickets and the unit test are separate packs, made for these lessons. Lessons 13.8 to 13.11 are taught in 3rd grade in some states only: polygons to the octagon (Virginia), lines, rays and angles (Florida, Georgia, Indiana, Oklahoma, South Carolina), lines of symmetry (Florida, Georgia) and solid figures and unit cubes (Oklahoma, Texas); skip the ones your class does not learn.

At Home

Teaching at home? Use the warm up and the "Try it together" step as a short lesson, and the "Words to use" as the way to talk about it. Grid paper, a ruler, the corner of an index card and paper shapes to fold are all you need. 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
Keep grid paper and square tiles out for every perimeter lesson
Give every student an index card to check right angles
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:

2.G.A.1 Draw and spot shapes with given features, like a number of angles or faces, and name triangles, quadrilaterals, pentagons, hexagons and cubes.
3.MD.C.7a Tile a rectangle with whole-number sides and show that the number of tiles matches multiplying its length by its width.
3.MD.C.7b Multiply length by width to get the area of whole-number rectangles in story and math problems, and picture products as rectangles.
3.MD.C.7c Use tiles or area models to show that splitting a rectangle's side into two parts splits its area into two products (the distributive property).
3.MD.D.8 Solve perimeter problems for polygons: add side lengths, find a missing side, and compare rectangles with equal perimeters but different areas, or the reverse.
3.G.A.1 See that shapes like rhombuses, rectangles and squares share features, such as four sides, that make them all quadrilaterals; draw quadrilaterals outside those groups.
4.G.A.1 Draw and find points, lines, line segments, rays, right, acute and obtuse angles, and parallel and perpendicular lines, including in flat shapes.
4.G.A.2 Sort flat shapes by whether they have parallel or perpendicular lines or angles of a certain size, and recognize right triangles as a group.
4.G.A.3 Find a line of symmetry, a fold line that makes two matching parts; pick out shapes that have one and draw their lines of symmetry.
