In this quiz, a large square is divided into 100 small squares of equal size. Few squares are painted yellow and the question is to find what fraction does the painted square represent in this whole lot. It is easy to find the fraction because all that is required is to count the total number of squares and the number of painted squares. After finding the counts one has to simply divide the count of painted squares to the total numbers. If the fraction thus formed appears to have any common factor between numerator and denominator, then the answer should be chosen such that it represents the option exactly after removing that common factor.

Finding fractions with 100 squares

Fractions can be a tricky concept for kids to understand, but a helpful way to visualize them is by using a grid of 100 squares. Each square represents one unit, and the fractions can be shown by shading in a certain number of squares.

For example, let’s take a look at the fraction 1/2. This fraction can be represented by shading in 50 squares out of the 100 squares. You can imagine that the 100 squares represent the whole, and the 50 squares that are shaded in represent half of the whole.

Another example, let’s take the fraction 2/5. To represent this fraction, you would shade in 40 squares out of the 100. You can imagine that the 100 squares represent the whole and the 40 squares that are shaded in represent two out of five parts of the whole.

You can also use the grid of 100 squares to help understand equivalent fractions. Equivalent fractions are fractions that have the same value, even though their numerators and denominators may be different. For example, 1/2 is equivalent to 2/4. To see this, you can imagine shading in 50 squares out of the 100 squares to represent 1/2. But you can also think of this as shading in 25 squares twice, which is 2/4.

You can also use the grid to understand mixed numbers, the combination of whole numbers and fractions. For example, the mixed number 1 3/4 can be visualized by shading 75 squares out of the 100 squares, which represents 3/4 and leave 25 squares unshaded, which represents the whole number 1.

Another interesting way to use the grid is to help kids understand the meaning of adding and subtracting fractions. For example, let’s say we have the fractions 3/4 and 1/2. To add these two fractions together, you can imagine shading in the 3/4 portion of the grid, then shading in the 1/2 portion of the grid. The shaded area represents the total fraction, which is 5/4. To subtract them, we need to remove the 1/2 part of the grid from the 3/4 part. Now we have 1/4 left.

It’s important to note that the grid is not meant to be used for multiplying or dividing fractions. As those operations may not have a whole number result and cannot be represented by a grid of 100 squares.

I hope this explanation helps you understand how fractions can be illustrated with a grid of 100 squares. It’s a great visual tool to help children understand the concepts of fractions, equivalent fractions and mixed numbers, as well as help them understand the basic operations with fractions. Remember, practice and repetition are key, so be sure to have your child practice using the grid with different fractions, and encourage them to create their own examples as well.
