What is the process to divide a total number of items equally among a group?

Back

Division is the process used to distribute a total number of items equally among a group. For example, if you have 24 markers and want to divide them among 6 classrooms, you would calculate 24 ÷ 6 = 4 markers per classroom.

How do you find the remainder in a division problem?

Back

The remainder is what is left over after division when the total cannot be divided evenly. For example, in 25 ÷ 4, the quotient is 6 and the remainder is 1, because 4 goes into 25 six times (24) with 1 left over.

What is a fraction?

Back

A fraction represents a part of a whole. It consists of a numerator (top number) and a denominator (bottom number). For example, 1/2 means one part out of two equal parts.

Front

How do you subtract fractions with different denominators?

Back

To subtract fractions with different denominators, first find a common denominator, convert the fractions, and then subtract the numerators. For example, to subtract 1/2 from 4/5, convert them to 10/20 and 8/20, then subtract: 10/20 - 8/20 = 2/20 = 1/10.

Front

What is the cost calculation for multiple items?

Back

To find the total cost of multiple items, multiply the cost of one item by the number of items. For example, if one sweatshirt costs $15 and there are 32 members, the total cost is 15 x 32 = $480.

Front

What is an equation?

Back

An equation is a mathematical statement that asserts the equality of two expressions. For example, 3 + 4 = 7 is an equation stating that the sum of 3 and 4 equals 7.

Front

What does it mean for two numbers to be equal?

Back

Two numbers are equal if they represent the same quantity. For example, 2 + 3 = 5 and 5 = 5 are equal statements.

Front

How do you identify the relationship between two fractions on a number line?

Back

To identify the relationship between two fractions on a number line, compare their positions. The fraction to the left is smaller. For example, 2/6 is to the left of 5/6, so 2/6 < 5/6.

Front

What is the concept of 'donating the remainder'?

Back

Donating the remainder means giving away what is left after distributing items equally. For example, if 27 markers are distributed among 12 classrooms, the remainder can be donated to one classroom.

Front

What is the importance of finding a common denominator in fraction operations?

Back

Finding a common denominator is crucial for adding or subtracting fractions, as it allows you to combine fractions with different denominators into a single fraction.
