In this unit on geometric measurement, students build on the work they have done with area and perimeter and extend it to three-dimensional solids. They will improve their abilities to reason spatially as they learn about the relationships among faces, vertices, and edges of rectangular prisms and how to make and label drawings of boxes. Students also learn to make sense of and use formula.

In this unit, students explore percents in depth and see how it is linked to the study of proportionality. They will make connections to number concepts and algebra as they develop their understanding of percents, connect percents to different representations of the same number using fractions and decimals, and use a variety of models including double number lines, bar models (tape diagrams), and equations to make sense of situations that involve percents.
In this unit on measurement, students are actively engaged in the measurement process and connect it to their own personal worlds. Students go ‘In Search of the Yeti” as they learn about perimeter, area, and volume.

In this unit, students begin their exploration of probability as a measurement of the likelihood of events. They move beyond performing simple probability experiments to an understanding of experimental and theoretical probability and the Law of Large Numbers. Students also experience what it means for a game to be fair as they create their own games.

In this unit, students learn about algebra as a set of concepts tied to the representation of relationships either by words, tables or graphics. They extend their notion of variable from a letter in an equation that represents a number to a more broad definition, that of a quantity that varies or changes. Students also study constant and varying rates of change as an intuitive introduction to slope.

This unit provides an introduction to fractions, focusing on the meaning of mathematical operations in contextual situations rather than learning algorithms to perform computations. Students will learn the relative sizes of fractions and make estimates based on their mathematical thinking when ordering, comparing, adding, subtracting, multiplying or dividing two or more fractions.

This unit provides an introduction to the decimal numeration system, focusing on conceptual understanding and operations with decimals. Students will learn how the powers of ten are used to create decimals and understand the role of the decimal point as the marker for the end of whole numbers.

In this unit, students explore 2- and 3-dimensional shapes with a focus on their properties, relationships among them, and spatial visualization. The reasoning skills that they build upon in this unit help them to develop an understanding of more complex geometric concepts.
