Multiplying Decimal Models How To Teach Students To Multiply Decimals
Multiplying Decimal Models How To Teach Students To Multiply Decimals These drawings are the easiest to use when modeling the multiplication of a decimal by a whole number. for example, if i give the problem 0.42 x 5, students can draw five blobs, label each 0.42, and move on. the difficulty with this strategy is that it does not lead the students towards the product for this problem. 6. how to teach multiplying decimals: play “solve the room” for active learning. keep your students moving and thinking with a solve the room activity. in this activity, students solve decimal multiplication problems that are posted around the room. this gets them out of their seats and actively engaging with the material.
Multiplying Decimal Models How To Teach Students To Multiply Decimals There are 3 common strategies for multiplying decimals: standard algorithm (also called the traditional method or "how i learned when i was a kid") a visual model using hundredths grids. an area model. in the videos below, i'm going to take you through a few sample problems using each of the strategies listed above. They love this one a lot! okay so start with following the same way as lattice method above. place the 35 (without the decimal) and then 27 on the right side. make sure it is on the right side. then multiply the counter parts like you just did in the partial products. 3 x .20= 0.60. .5 x .20 = .100. 3 x .07 = .21. .5 x .07 = 0.035. We use models after students estimate products with decimals. students are given task cards with two decimal factors and the digits of the product without the decimal point. students use estimation to determine where the decimal point belongs in the product. example: 2.3 x 5.1 gives a product with the digits 1173. Then, show students how to shade in the models to represent various decimals (e.g., 0.4, 0.12). write each number in decimal and fraction form before shading in the model. explain to students that today they will use models to multiply decimals in the tenths place. ask students specific questions to help them talk about their background.

Decimal by decimal. 4. area model. this is the best way for decimal by decimal multiplication to be shown conceptually. because area models work with whole numbers so well, then we can apply the same idea to decimals. we are going to model 0.3 horizontally and 0.4 vertically. the overlap is the product = 0.12.
