Think beyond worksheets. There are simple manipulative lessons that can be made in minutes using everyday classroom materials.
In this video, I actually used some old envelopes I had laying around to create a single set for a student to practice the flow of solving one step equations. A teacher can adapt this to a scale-able classroom activity by writing or typing the problems in columns, using a paper cutter to create the sets and place them in baggies for each child or pair. Single step equations are the cornerstone of Algebra, students need to master this concert.
The idea is simple. Use similar numbers and create a set of problems, single step taken for solving, and the solution. This style is more challenging than asking them to solve problems on paper or a computer because they have to compare and contrast options to make decisions. So, they are not only discovering why steps match but also why others do not match. Conversations will spark between students and teachers about why they did not choose addition or how they eliminated coefficients with their selected steps, for example.
As a follow up lesson, take kids to the next level and give them paper and scissors or index cards and ask them to create a problem set for their partner to match. Ask kids to think outside the box and try to create problems that might make their partner fall for common mistakes!
