UXO game to practice
'Rectangles: how much bigger' for 4th grade

Compare the area of 2 rectangles and calculate the difference

To calculate the area of a rectangle, you multiply its width by its height. In this topic, you are asked to calculate the area of two rectangles and determine how much bigger the larger one is than the smaller one. To do so, you will need to calculate the area for both rectangles then subtract the smaller area from the larger. Your answer will be in units square.

Let's say you have 2 rectangles, one with dimensions of 5 m x 3 m and the other with dimensions 6 m x 4 m.

To calculate the area of the rectangles, multiply width by height.

The area of the first rectangle is:

Rectangle 1: Area = 5 m × 3 m = 15 m²

The area of the second rectangle is:

Rectangle 2: Area = 6 m × 4 m = 24 m²

The second rectangle has a bigger area than the first rectangle. The difference in area of the two rectangles is:

Difference in area = 24 m² - 15 m² = 9 m²

So, you can see that the second rectangle has an area 9 m² greater than the first rectangle.


This topic asks you to calculate the area of two rectangles and work out the difference in size. Your answers should be in square units such as square centimeters (cm²) or square meters (m²).

With our UXO math game you will be practicing the topic "Rectangles: how much bigger" from 4th grade / Measurements / Calculate & compare. The math in this game consists of 16 questions that ask you to compare areas of rectangles and say by how much one is bigger than the other.

UXO is a click to clear game with multiple targets at different levels

Large thumbnail for math game UXO

UXO is a fun game to learn math where you attempt to knock over all the target objects while avoiding clicking / tapping on the bombs.

After each level, win an additional 50 points by correctly answering a math question from your selected topic. Wrong answers lose you 20 points but you can answer multiple times. Each level lasts 30 seconds: if you haven't cleared all the targets in that time, you lose 50 points. High scores can be added to the UXO leaderboards.


Notes

  • This is a fast-paced game of clicking or dragging over moving targets.
  • Also suitable for tablets and mobiles (it's actually easier than with a mouse)
  • Answer math questions correctly for a higher score
  • Hit all the targets in 30 seconds or you lose points.
