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 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-dimensional shapes and in doing so, discover properties of these shapes rather than memorize definitions given to them.
This unit specific non-consumable kit includes items that last from class to class and
