Properties of Two-Dimensional Figures helps Grade 5 students build confident understanding through visual models, worked examples, and guided practice.
Students understand that attributes belonging to a category of two-dimensional figures also belong to all subcategories. For example, all rectangles have four right angles, so all squares also have four right angles.

Volume of Composite Figures helps Grade 5 students build confident understanding through visual models, worked examples, and guided practice.
Students recognize that volume is additive and find the volume of solid figures composed of two non-overlapping right rectangular prisms. They decompose complex figures into simpler parts and add the volumes.

Understanding the Coordinate Plane helps Grade 5 students build confident understanding through visual models, worked examples, and guided practice.
Students use a pair of perpendicular number lines (axes) to define a coordinate plane. They learn the terms origin, x-axis, y-axis, and ordered pair (x, y), and understand that the first number tells horizontal distance and the second tells vertical distance from the origin.

Finding Volume Using Formulas helps Grade 5 students build confident understanding through visual models, worked examples, and guided practice.
Students find the volume of right rectangular prisms using the formulas V = l × w × h and V = B × h, where B is the area of the base. They connect the formulas to counting layers of unit cubes and apply them to solve problems.
