This case shows a teacher facilitating student discussion and students posing clarifying questions to their peers to understand how equations of periodic data were created.
In this case the teacher is facilitating students working with perimeter and area, and students are modeling these measurements using manipulatives to create polynomial expressions.
In this case the teacher is facilitating students in developing a concrete understanding of non-perfect square roots and students are using manipulatives to see differences between perfect and non-perfect squares and then determining the fractional/decimal value of the non-perfect square.
In this case the teacher is facilitating students using stream tables to learn about erosion and weathering and students are doing the activity, observing, sketching, and comparing results to their predictions.
In this case the teacher is facilitating mostly ELL students working together on the surface areas of rectangular prisms and the students are creating paper nets to form cubes, drawing hexomino nets on grid paper first to help them with the visualization, and then using words to explain their thinking.
