4 - Formula for Volume Introduction

Rational

Strand Measurement Code Specific Expectations Determine, through investigation using stacked congruent rectangular layers of concrete materials, the relationship between the height, the area of the base, and he volume of a rectangular prism, and generalize to development the formula.

Material

Volume worksheet. Math Makes Sense textbook. Centicubes or simmilar

Vocabulary

height, length, width, volume, dimensions, formula

Hook

In general, you can't figure out the volume of something using centicubes. Instead you must use a formula and work it out using a formula
Say you want to give your teacher a present of a Tim Horton's cup. You want to make a box big enough to hold the cup. Calculate the volume of the cup.
