Soon Yolanda must make an important decision: whether to try to find another harmonica for Andrew, or to obey her mother
In this unit, students explore algebra as a system of concepts used to represent relationships. They learn to express these relationships using words, equations, tables, and graphs. By exploring world records, some of the most astonishing feats ever achieved, they see algebra in action and even start imagining their own record-breaking possibilities. They also learn about algebra as a style of mathematical thinking for formalizing patterns of change. They extend their notion of variable from a letter in an equation that represents a number to a broader definition, that of a qu
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
