Just as the sun appears in different places in the sky throughout the day, changes big and small happen around us all the time. What other changes happen in nature throughout the day? How do the tides rise and fall? How do flowers change? What happens to the temperature?

In this unit, students are introduced to ratios, rates, proportional reasoning, similarity and congruence. Students explore ratio as a comparison of two quantities. They discover that if the ratio between the corresponding side lengths and angle measures of two figures is 1:1 (i.e., the measures are identical), then the geometric figures are congruent. They learn that for two figures to be similar, their corresponding side lengths must be in proportion and their corresponding angles must be congruent. Students also explore the relationship between congruence and similarity, learning that al
The Student Mathematician’s Journal allows students to explore simulated or real-life problems and help them to think, write, and read like mathematicians. It encourages students to reflect on what they have learned in each lesson, think deeply about mathematics, and communicate in writing on worksheets.
In this unit students develop their number sense with a focus on a deeper understandin
The Student Mathematician’s Journal presents simulated or real-life problems that encourage students to think, write, and read like mathematicians. They are asked to reflect on what they have learned and communicate in writing on worksheets.
In this unit, students explore two- and three-dimensional shapes and the relationships among them. The reasoning and spatial-sense skills they use will help the
