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 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
