Remembering the formulas to calculate the area or volume of different geometric shapes is not easy. Isn’t it?
How about you have a sticky note handy, to get started.
Calculating the area of a rectangle or a square can still work, but as soon as you tackle the parallelogram or the trapezoid, the formulas are more complicated to remember.
Same for volumes. Calculating the volume of a straight block or a cube can be done almost without thinking too much, but as soon as you move on to the cone or the ball, the brain begins to heat up slightly.
In order to help our children complete their geometry exercises, we often have to take out the lesson notebooks or books or start the computer to start researching on the internet. It is better to print these formulas once and take them out as needed, because we may not have the patience to learn them by heart for our children.
This sheet in A4 format and in PDF brings together most of the common formulas for calculating areas and volumes in relation to geometry exercises.
You can print it as you wish and of course keep it aside to take it out if necessary.
