Draw a place value chart on the whiteboard and demonstrate to students how to place each digit in the correct place. Students have already used place value charts for whole numbers, so point out that now we’ll simply adjust these charts to use them for decimals to show the place of digits in numbers.įor example, let’s say we want to compare 4.859 and 4.869. Comparing Decimals Using Place Value ChartsĮxplain that we can compare decimals with the help of place value charts. For example, to find the value of 7 in 9.078, we’ll locate the place value of 7.

The decimal places also indicate the position of the digits. Point out that the digits that are after the decimal point represent the decimal places. Ask students to identify the whole number part and the fractional part in each given decimal. Write a few examples on the whiteboard, such as 2.5, 1.23, 0.52, 0.002, etc. So start off your lesson on decimal place value by defining a decimal as a number that consists of a decimal point, followed by digits whose value is smaller than one. Students are already familiar with decimals and what they represent, but it’s always good to refresh their memory. Strategies to Teach Decimal Place Value What Are Decimals? Students may initially find decimal place value concepts confusing and mix up the tenths with tens or hundredths with hundreds, but don’t despair! If you’re teaching this, we’ve outlined a few cool teaching strategies that will help make the learning process smooth and fun! Read on! They also gain fluency in rounding off decimals.
