Partial Products with Decimals

Module 10, Lesson 4









Students pick one of each card (whole number and a decimal) to create a multiplication expression. Students write the expression as partial products and calculate the answer. If students need support, encourage them to draw a model.

Extra Help: 
Students use tenths grids or number lines to model multiplying a whole number x a decimal.

Extra Practice
Students work in pairs and choose a recording sheet (grids or number lines). On their turn, students roll a cube and pick a card to make a multiplication problem and represent it on their recording sheet.  After 5 rounds, the partner with the greatest sum of products wins.  You can have students switch recording sheets the next time they play, or have everyone work on one type of sheet (grids or number lines.)

Multiplying Decimals

Module 10 
Multiplying Decimals Practice
5.NBT.7

Students draw cards to multiply together. You can have students use only the cards with tenths, or the cards with hundredths, or a mix of both, depending on where you are in your lesson sequence. Students earn a point for calculating the correct product.  The student with the  most points after 5 rounds is the winner.

Fraction and Decimal Equivalents: Multiplying Tenths by Hundredths

5.NBT.1,2,7
Module 10



Students take turns drawing two fraction cards and writing the decimal equivalent. Students find the product of the two numbers, recording each expression as both a fraction and a decimal.  If they are correct, they earn a point.  The with the greater product earns a point for that round.

Students draw two playing cards A-9 to create two tenths.  3=.3   The then use the hundredths grid to multiply the two decimals together. Students can either both solve it and compare or take turns.

Grocery Shopping and Multiplying Decimals

5.NBT.7
Module 10

Students find 9 items on grocery store ads and write them along the recording sheet on the left side.  They find out how much they would cost if you bought 1 of those items, then 2 of those items, all the way to 9 of the item.  You can have them find all of the costs or 1 of the first, 2 of the second, three of the third and so on.  Sample ads are attached to either print or project on the board.

Decimal Multiplication Hundredths

Module 10, Lesson 4

Differentiation Activity
5.NBT.7

Students generate 3 digits between 1-9 to create multiplication expressions. To generate digits, students can use playing cards (A-9) or virtual dice. (To make it easier, share the link to the digital dice with students using Google Classroom.)

Once they have their digits, students create three different expressions. Expressions must be a whole number x a hundredth.  For example, if a student has the digits 3, 2, and 4 they can create: 3 x .24, 2 x .34, or 4 x .23. Students calculate the products for each f their expressions and compare with a partner.

Multiplication of Tenths

5.NBT.7
Module 10
Differentiation Activity

Students draw a card from each pile.  They multiply the decimal fraction by the whole number using the number line.  They record their product.  After five rounds, the students add up all their totals, and the student with the greatest total is the winner.
