Multiplying Decimals Using Base Ten Blocks A demonstration of how to use base 10 blocks to model multiplying decimals by a whole number and decimals by decimals. First, we needed to establish the value of the base 10 blocks. when using base 10 blocks with whole numbers, the flat typically represents 100, the rod represents 10, and the cube represents 1. but when we shift to decimals, the materials take on new values. with decimals, the flat becomes the whole, meaning that it is now 1.
Mnes How To Multiply Decimals Using Base 10 Blocks Youtube This is a video of grade seven students explaining how to multiply decimals using base ten blocks. it goes along with the pearson grade 7 math makes sense t. Two grade 7 students explain how to use base ten blocks to multiply decimals. One thing to remind students is that ten base 10s or 100 unit cubes equals 1 whole. 2. number lines. a number line is another way to model multiplying a whole number times a decimal. the decimal factor will be the length of the jump and the number of jumps is the whole number. this is great for smaller numbers. Multiply: possible answers: correct answer: explanation: when multiplying decimals, we can use our base ten blocks to create an area model. to do this, we want to use our hundreds, or one whole, block: is equal to three tenths. remember, our one whole block is made up of ten tenths. we can shade in , or three tenths blocks, of the whole.

When you multiply a whole number by a decimal, you are also making equal groups! you can use the same strategy when multiplying decimals by decimals. arrange your base ten blocks to show the 2 factors (length x width). About base ten blocks. base ten blocks (also known as "base 10 blocks" and "place value blocks") is an online mathematical manipulative that helps students learn addition, subtraction, number sense, place value and counting. it lets them investigate how to regroup and solve problems with whole numbers and eventually fractions and decimals.
