Multiplying Decimals Using Base Ten Blocks
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.
Multiplying Decimals Using Base Ten Blocks Multiplying Decimals 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. Tips when teaching decimals. use base ten blocks and grids to represents the decimal fractions and decimal numbers. use money and discuss how the coins represent ones, tenths and hundredths. explain that the decimal part refers to a fraction of a whole dollar as opposed to a whole number of nickels, dimes, or quarters. Use a dry erase marker to draw a decimal point between the ones place and the tenths place. or you can print the patterns in my build a number freebie to create the place value mat on 2 sheets of 8.5″ by 11″ paper. seat your students in teams of four and give each team one set of base 10 manipulatives.

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. 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.
