Objective: At the end of this lesson, students should be able to divide decimals by multiples of ten. When dividing decimal numbers by multiples of 10, the place value of the digits change, the number becomes smaller. The place value of the digits move from left to right making it look like the position of …
Objective: At the end of this lesson, students should be able to estimate answers to questions involving decimal addition and/or subtraction. To estimate means to make an informed guess. Decimals can be estimated by first rounding the decimal numbers involved to the nearest whole number, tenth, hundredth or thousandth before adding or subtracting. Example 1 …

Objectives: At the end of this lesson, students should be able to: Identify decimal numbers between any two consecutive whole numbers. Know the decimal numbers that exist between any two consecutive decimals. Read and write decimals on a number line. Fill in gaps in decimal sequences by identifying and applying the rule. Decimal number lines …
Objective: At the end of this lesson, students should be able to arrange decimals in increasing or decreasing order of size. To order decimals means to arrange decimal numbers in an organized manner. This implies arranging decimals in ascending or descending order. From the previous knowledge applied in comparing decimals, we can identify the largest …
Objective: At the end of this lesson, students should be able to compare decimals using. >, < or =. When comparing decimals, you identify which decimal is greater than (>), less than (<) or equal (=) to the other decimal to which it is being compared. Example 1 Compare: a) 3.425 and 0.648 b) 18.291 …
Objective: At the end of this lesson, students should be able to expand decimals into simpler fractions. Decimals consist of simple fractions that have been added up. They can therefore be broken down into these simpler fractions. Example 1 Expand 0.3796 to its simpler fractions. Solution Example 3 Write the decimal 4286.087 as a …
Objective At the end of this lesson, students should know and understand the place value and value of decimal numbers. Decimal Vocabulary Decimal/Decimal number: – Is a number that represents a whole number and part of a whole by separating them with a point. Decimal point: – Is a point separating the ones and tenths …
Objective: At the end of this lesson, students should be able to write decimals as fractions. Decimals can be written as fractions by using an approach similar to the knowledge used when changing fractions to decimals. Example 1 Write the following decimals as fractions. a) 0.7 (b) 0.53 …
