Project-based Learning: Soda Can Redesign, a Lesson on Volume

Project-based Learning: Soda Can Redesign, a Lesson on Volume

Comments 0 Comment

This is a fun lesson I do with sixth graders where students redesign the soda can. After reviewing volume of rectangular prisms, students determine the volume of a can of soda in cubic inches. They use this volume to re-design the soda can so that their can has the same volume. Students will need to use the area of polygons such as rectangles, triangles, parallelograms, and trapezoids in the design of their new can. They begin by creating a net…

Equivalent Fractions on the Multiplication Matrix

Equivalent Fractions on the Multiplication Matrix

I’d been staring at equivalent fractions for eons and never knew it. Check out this multiplication matrix filled with them! Way cool! Starting simply, look at the first two rows in the upper left.  The number in the first row (numberator) is ‘1’ and the number in the second row (denominator) is ‘2’.  Those numbers represent the fraction 1/2.  All the numbers in the two rows to the right reflect the equivalent fractions. This works for any two numbers picked…

Just finished a unit and want your students to review what they learned? Getting ready for the chapter test? Just want to have fun? Jeopardy is a great way to review and reinforce what students have been learning. This photo shows some of the categories I use in the primary grades. The ones at the bottom show additional categories. Pretty much anything you’ve been learning can work. The students in my classroom are already set up in groups of 4-5….

Number Theory: Square Numbers

Making rectangular arrays with tiles is a great visual way to have students understand multiplication as repeated addition. And since we’re making arrays anyway, why not tie in square numbers. A square number is: 1) A number that can be expressed as the product of the same two numbers. 2) The product of a number multiplied by itself. When making rectangluar arrays, square nuumbers (1, 4, 9, 16…) always make a square. Besides, there are some very neat patterns that…
