The van heile theory and development of geometric thought is very helpful in structuring and teaching geometry.
1. Give an example of how a learner on level 1 will define a rectangle.
2. Give one example of how a learner on level 2 will define a rectangle.
3discuss it's meaning in the context of the classification of quadrilateral as a learner on level 2 would do it.
The phrase “instrumental understanding of mathematics” means that
A particle moves so that its position vector is given by r =cosωti+sinωtj. where ω is a constant.
a)Show that the velocity v of the particle is perpendicular to r, and the velocity acceleration a is directed towards the origin and has magnitude proportional to the distance from the origin.
b) Show also that r × r is a constant vector.

Question: Generalized geometrical incidence?
A software designer is mapping the streets for a new racing game. All of the streets are depicted as either perpendicular or parallel lines. The equation of the lane passing through A and B is -7x + 3y = -21.5. What is the equation of the central street PQ?
ABCD is a quadrilateral with G and H the mid points of line DA and DC respectively. Show that line AB + line DC = 2GH
9 Draw pictures showing how 39 × 6 could be modelled with base-10 blocks or with areas on base-10 grids. (Use at least two of the methods.)
