Pre-K-2
Students review this unit by creating, decomposing, and comparing sets of zero to 10 objects and by writing the cardinal number for each set.
6-8
This lesson introduces relationships between measurement and geometry. The activities build on students' prior knowledge as students work with partners and as a whole class to identify and classify terms to develop their understanding of measurement.
6-8
Students learn about ratios, including the “Golden Ratio”, a ratio of length to width that can be found in art, architecture, and nature. Students examine different ratios to determine whether the Golden Ratio can be found in the human body.
6-8
Students learn to write and solve proportions by gathering data and calculating unit rates.
6-8
Students learn the basics of the metric system. They identify which units of measurement are used to measure specific objects, and they learn to convert between units within the same system.
6-8
Students experiment with units of liquid measure used in the customary system of measurement. They practice making volume conversions in the customary system.
6-8
Students extend their knowledge of proportions to solving problems dealing with similarity. They measure the heights and shadows of familiar objects and use indirect measurement to find the heights of things that are much bigger in size, such as a flagpole, a school building, or a tree.
6-8
Students use real-world examples to solve problems involving scale as they examine maps of their home states and calculate distances between cities.
3-5
In this lesson, students conduct a survey and create bar graphs from the data they have collected.
3-5
Students conduct a survey and create pictographs and line plots. They also determine the number of possible combinations.
