Solving an equation is the art of creating simpler equivalent equations using properties of equality. Here, classes see that solving an equation is not always as easy as guessing. The lesson presents linear equations that scholars must...

Test mathematicians' knowledge of adding fractions with a brief assessment that challenges them to play teacher while correcting a peer's work. Scholars examine Carl's mathematical response, identify where he went wrong,...

Young mathematicians demonstrate what they know about measurement with a four-task assessment that focuses on estimation, length, and inches.

Don't table the discussion on equivalent ratios — do it now! Scholars create tables of equivalent ratios to represent contextual problems. Pupils go on to use the tables to answer questions within the context. The lesson is ninth in a...
