Students will create 3-D figures and slice them to discover the cross section.
Students will manipulate figures to discover how transformations can move figures to specific places.
A rich task where students will perform a task and count how many times it can be done in an allotted time. They will then use this to discover and practice how to find unit rates from complex fractions and even take it to the next level of feeding into understanding where slope comes from if desired.
A rich task to discover and practice how to find like terms and then simplify expressions.
A rich task to discover and practice how to add and subtract fractions through modeling with fraction strips.
In my opinion this is the absolute best activity to review problems or practice concepts. This is an engaging activity that can be played as a game or not depending on your preference.
This is a discovery rich task that leads students to discovering the general formula for the volume or a rectangular prism, triangular prism, and cylinder: V = Bh (volume = area of the base times the height).
This is a great rotational symmetry rich task that comes with manipulatives that you can print out and use to give your students a visual and tactile approach to help learn a concept that is very difficult for many students who are not visual.
