- Identify types of triangles (KnowledgeBox)
2. Establish the formulas for areas of triangles, rectangles and parallelograms and use these in problem solving.

- Geoboard (National Library of Virtual Manipulatives)
- Triangle Explorer (Shodor Interactive)
- Area of a triangle (Cut-the-Knot)

- Area of rectangles (KnowledgeBox)
3. Demonstrate that the angle sum of a triangle is 180 degrees and use this to find the angle sum of a quadrilateral.
- Interactive triangle (MathsWarehouse)
- Angle sum theorem (Sum of three angles in a triangle always equal 180 degrees)
the game teachs you how to do the area of a triangle
it teacches you about how to calculate the area of a triangle.
This game was very fun and i learnt alot to. Like how to work out the area of a triangle.
I found them pretty easy except for when none of lines of the triangle where horizontal or vertical.
the game was good and i learnt how to get the area of triangle faster.
I found the triangle game pretty easy except for the last one when the lines weren’t on the grid properly and it came up with decimals.
the game is good i learnt how to get the area of a triangle
I learnt that the area of a triangle is 1/2 of the base times hight.
The triangle area game was a easy but some parts of it was a bit hard.
I found this game Area of triangles easy. I had some trouble on the last one beacause the traingle wasnt in the whole rectangle.
The game was really good because I learnt a new way to find out the area of a triangle instead of just having a rough estimate.
I learnt that you have to calculate the base before the hight.
i area of triangles
Hello,
Today I have learnt that base and height is the area.
By Emily
I learnt that you have to half base times height. This game is very fun and i learnt lots for it.
I liked the Area of triangles app because its easy but I still learn a whole lot from it like how to find the area of a triangle and its easier than it looks.
I learnt that in a triangle you half the base and height to get to area
I learnt that how to find the area of a triangle. I also found this game fun.
I liked the base ball game with the triangls and i like the area of triangles game i lernt about the area of triangles :).
