ROCK FALL game to practice
'2D shapes from lengths, angles' for 5th grade

Identify 2D shapes from information on sides and angles

Many regular 2D shapes can be characterized in terms of the length and number of sides plus information on the angles of their vertices.

For instance, say we have a shape that has 4 equal length sides and 4 equal angles of 90 degrees. Given that it has 4 angles of 90Β° it must be a regular quadrilateral. Knowing that it has 4 equal length sides we can deduce that it is a square.

If you have a shape with 3 sides of unequal length and 3 angles that add up to 180 degrees, you know immediately that it has to be a triangle (internal angles of triangles add up to 180Β°). The fact that the sides are of unequal length means it cannot be an equilateral triangle (which has equal length sides) or an isosceles triangle (which has 2 sides the same length) so we know it must be a scalene triangle.

In this topic you are given as question a description of a shape in terms of it's sides and angles. You have to decide which shape that description applies to. The shapes that are covered include square, rectangle, different types of triangle, rhombus, parallelogram, kite, pentagon, hexagon, etc.

With our Rock fall math game you will be practicing the topic "2D shapes from lengths, angles" from 5th grade / Shapes / Identifying shapes. The math in this game consists of 16 questions that ask you to for each set of lengths and angles identify the correct 2D shape that is described.

Large thumbnail for math game Rock fall

ROCK FALL is based on the road traffic warning sign for falling rocks - a sign that seems a bit less useful than somebody getting up there on that cliff and actually doing something about it... Anyway, the rocks are falling and it is your job to stop them hitting the road below, or at least stopping them hitting the road below too many times and breaking it. Smash the rocks by clicking or tapping on them (not so easy in real life of course) - they will turn into snowflakes and float gently down into nothing.

There are 4 rocks to stop and not much time to do it (if you want to get a good score and get on the leaderboard). This game is fun and fast and requires good reflexes and a good strategy. Plan to break the smaller rocks first if you want a good score because the rocks fall faster as the game progresses. It also helps to decide where on their path you plan to click / tap the rocks.
