Solving Equations with Unknowns on Both Sides Version 1(notebook)
A_GualdaA_Gualda

Solving Equations with Unknowns on Both Sides Version 1(notebook)

(0)
2 lessons: Lesson objectives to solve equations with unknowns on both sides, including equations with brackets. Includes; teachers’ notes on using interactive elements, step by step guide, worked examples and practice questions. The big idea is to rewrite both sides of the equation to eliminate like terms. Hence the phrase “Same Value, Looks Different”. It uses money to show that you can can have the same value, but in different ways. Hence, you can rewrite any equation in any way as long as you do not change the value.
