The students should arrange their squares so that there are three rows of two squares. Ask students how you can figure out how much carpet you need to cover this space and ask them to show you how they can cover the space with their squares. You can also have the squares on their desk when they enter for class to save time. Hand out packs of six small, 2D squares to each set of partners. Walk through what area means the number of squares that cover a given 2D space. Volume of a Right Rectangular Prism Worksheetīefore you begin, review with students how to find the area of a rectangle.One copy of the Volume Worksheet for each studentĬlick the link below to Download the Worksheet:.A small rectangular prism brought in by students – for example, a toothpaste box, raisin box, etc.Place value blocks separated into containers for individual use or larger containers for groups to share.A pack of six small, 2D squares for every 2 students.Each student needs their math notebook or a piece of paper.Set up for the Lesson: Volume of a Right Rectangular Prism This hands-on lesson for exploring volume is what I use to make sure students start out with a concrete understanding of a cubic centimeter and can visualize what they’re actually measuring when they use the formula for volume. It’s an easy reference to give students a concrete understanding of what they are measuring. Now, I keep a set of place value blocks out at all times when exploring volume. This is the unit label we have been talking about for days. “It’s a blue box.” “A cube.” When I told them it is a cubic centimeter there was a chorus of, “Ohhhhhhh, that’s what you’re talking about?” When I asked them if they knew what it was, I got every answer in the book other than a cubic centimeter. To test my hypothesis that they don’t understand what a square centimeter is, I held up a single blue centimeter square place value block. We try to help them connect labels to what they see, but that’s often not concrete enough to really help students understand a unit like a square centimeter. My students didn’t understand what the label actually meant! When teaching Volume of a Right Rectangular Prism, we draw 3D figures on the board and students see them in their math books. For the longest time, I didn’t understand why this was the case. I have noticed that students often leave out the unit label when doing word problems or measuring.
