- video presentation (for balance) discussion
- Scales for visualizing the properties of equality. (Student action).
- Presentation of properties with mathematical symbols on the blackboard.
- Equation Solution (Students Action)
Students learn to solve first degree equations
Advisable age of students:
(Flexible according to the curriculum of specific country) 13
- use of variables,
- distributive property,
operations with algebraic representations
Materials:scales, balls, wooden toys in the shape of a cube, and parallelepiped, finger paints
PHASE A (10 min)
Video, discussion and student participation in relation to balance for understanding equality.
PHASE B (35 min)
Playing with the scales to balance each stage by adapting the various objects appropriately
PHASE C (45min)
Conclusions and discussion with students to understand the sequential steps in solving the equation
Comments, possible derivations, and prolongations of the proposal:
Each lesson plan can have more phases and each phase can be divided in further sub-phases in order to reach the learning objectives
