Mini Lesson (8:50 – 9:25)/(10:20 – 10:55) 
· T will tell students that Volume is a measure for 3D shapes. · T will tell student volume is the number of cubic units that can fit inside of a solid. (The number of cubes that fit in a shape) · T/S will show an example using cubes as manipulatives o Give students a rectangular solid and several one inch cubes o Ask students to fill the solid with cubes and to count how many cubes fit inside of the solid o Explain that this is the volume of the solid · T will tell students that while we can always find volume by filling a solid with cubes, we might not always have that available so there is a formula to help us. · T will share formula V = lwh · T will demonstrate how to find the volume of a shape using the formula o Demonstrate with the solid used with manipulatives o Show that the length of the shape is 6 because 6 cubes fit across the length o Show that the width of the shape is 4 because 4 cubes fit across the width o Show that the shape is 2 units high because two cubes are the same height as the solid o Multiply 6 x 4 x 2 to get 48 same as what we did when we filled the shape o Demonstrate another example without manipulatives § Identify the height, width and length but putting a H, L and W next to those measures § Multiply the three measures together to get the volume § Stop and discuss the units for volume – ask students to show the fingers for the exponent that represents “cubed” § Explain to students that since we are multiplying 3 dimensions together our units are cubic units (Relate to how area is square units) · S will find the volume of the shape · Connect volume with filling a shape
