One page to give on the first day of the unit on the area and perimeter of polygons, before any teaching. Its six questions are on what the unit builds on: adding mixed numbers and a whole number times a fraction (for fraction side lengths), the area and perimeter of a rectangle, half of a rectangle on a grid (for right triangles), two-digit products (for the formulas), units or square units (for the stories) and the perimeter of a polygon from its sides (for estimating perimeters). It has a Score line, and the key names the lesson each question leads into. The unit review and the unit test are packs of their own.
Give the pre-check on the first day and sort the class by what they missed. A student who cannot find the area and perimeter of a rectangle needs that before shapes made of rectangles; one who calls a perimeter square feet needs the "covering or going around?" talk before the stories. The half rectangle leads into the lesson where a right triangle is half a rectangle.
Use it to see what your child needs before the unit starts: ask how much fence goes around a garden 7 m by 4 m, and how much ground it covers.

A check to give before the unit on the area and perimeter of polygons, on the fractions, area and perimeter and multiplying it builds on. Students add mixed numbers, measure a rectangle, find half of a rectangle, multiply two-digit numbers, pick units or square units and add the sides of a polygon.
