Solving Equations Mystery Grids!
Use the clue cards to calculate the missing numbers in the grid.
Mystery 1: Solving simple, one step equations, e.g. 3a = 12
Mystery 2: Solving two step equations, e.g. 10 = 3a + 1
Mystery 3: A larger grid, with more difficult clues and including decimal and negative number solutions.
As an extension, students could make up their own mystery activity on equations.
This activity is good for homework as it is easy to check students have answered all the questions correctly at a glance.
CCSS: 6.EE.B.7 - Solve real-world and mathematical problems by writing and solving equations of the form x + p = q and px = q for cases in which p, q and x are all nonnegative rational numbers.
CCSS: 7.EE.B.4.A - Solve equations of the form px + q = r and p(x + q) = r fluently.
