When we multiply decimals our product or answer is lower than the factors.Įvery time they have multiplied in the past, they got a larger number. When doing this type of math work, it is essential that our children understand how they get an answer. In this example, we can see that 20 out of 100 squares have been colored in twice, so my answer is twenty hundredths or 0.20. The answer is everything that overlaps or was shaded twice. But this time we will color in the decimal horizontally so that they overlap. Next, we color in the next factor: five-tenths. This means we will color in four-tenths or four out of ten columns. Let’s look at the multiplication problem 0.4 x 0.5.įirst, we color in the first factor vertically. Multiplying decimals on the decimal grids is not as scary as it sounds. Task cards like these give children great practice in recognizing decimals on a decimal grid as well as modeling a decimal on the decimal grid. So to model this, we color in 5 rows out of the 10 rows or 50 out of the hundred squares. This works perfectly for decimals, which are categorized as tenths or hundredths.įor example, five-tenths (0.5) can also be written as 5/10 or 50/100. If your kiddos aren’t familiar with decimal grids, then jumping right into this activity may not be the best place to start.ĭecimal girds are one way of modeling decimals, and children need to know how to model a decimalbefore practicing multiplication on them.Ī decimal grid has 100 squares and 10 columns and 10 rows. Now gather up scissors and glue sticks and you will be ready to go. ![]() For example, if you choose to do page three then you will need to print off page four, as it has the models that correspond and will need to be glued on. Multiply Decimals with Grids Prep Work:įirst, choose the pages you want your child or children to do and print that page and the following page.

This multiplying decimals activity lets older kids enjoy cutting and gluing while using decimal grids to solve multiplying decimal problems. Getting out the glue and scissors just makes a math activity a little more fun. Young children love cut and paste activities. ![]()
