Activity No # 1. Introducing parallelograms
Laptop, geogebra file, projector and a pointer.
 * Estimated Time : 40 minutes.
 * Materials/ Resources needed:
 * Prerequisites/Instructions, if any:
 * 1) Knowledge of parallel lines, diagnols and angles.
 * 2) Basic figures like square, rectangle and rhombus.
 * Multimedia resources: Laptop
 * Website interactives/ links/ / Geogebra Applets
 * Process:
 * 1) The teacher can use this geogebra file to introduce parallelograms to students.
 * 2) She can move the vertices A or B or c and observe different parallelograms formed like square, rectangle and rhombus.
 * 3) Bring their attention to measures of sides, angles and diagnols.
 * Developmental Questions:
 * 1) Can you identify the figure ?
 * 2) How many sides does this figure have ?
 * 3) What do we call a figure with 4 sides ?
 * 4) Are all 4 sides equal ?
 * 5) What are parallel lines ?
 * 6) Identify the 2 sets of parallel lines.
 * 7) Spell out the differences between the figures formed with respect to sides, angles and diagnols.
 * 8) What common features do you observe in all figures/shapes formed ?
 * Evaluation:
 * 1) What are parallelograms ?
 * 2) Are square, rectangle and rhombus parallelograms ?
 * 3) How many pairs of parallel lines does a parallelogram have ?
 * Question Corner:
 * 1) Are all parallelograms quadrilaterals ?
 * 2) Is kite a parallelogram ?
