In this unit, students represent and analyze mathematical situations using algebraic symbols, they come to understand the basic notions of equality and equivalent expressions through informal problem-solving. They learn how variables are used to represent change in quantities and also to represent a specific unknown in an equation.
The Teacher Guide is designed to provide background information on the mathematics being taught in this unit, the learning environment, mathematical communication, and differentiated instruction. Also included:
It was a dark and stormy night; Meg Murry, her small brother Charles Wallace, and her mother had come down to the kitchen for a midnight snack when they were upset by the arrival of a most disturbing stranger.
"Wild nights are my glory," the unearthly stranger told them. "I just got caught in a downdraft and blown off course. Let me sit down for a moment, and then I'll be on my way. Speaking of ways, by the way, there is such a thing as a tesseract."
A tesseract (in case the reader doesn't know) is a wrinkle in time. To tell more would rob the reader of the enjoyment of
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
