Multiplying Decimals Anchor Chart For Elementary Math Vrogue Co Area model multiplication: 2 digit by 2 digit numbers. area model multiplication is also great when multiplying 2 digit by 2 digit numbers. again, it is important to break down both factors. let’s try it with an example. multiply 25 x 32. break down both factors so that they show tens and ones. 25 = 2 tens 5 ones or 20 5. 32 = 3 tens 2 ones. 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. The example in my multiplying decimals anchor chart is 3.4 rounds to 3, and 4.6 rounds to 5. thus 3×5=15, which is a good starting estimate for the answer. after getting the estimate, multiply the non rounded numbers without the decimal point. thus, multiply 34×46. this gives a product of 1564. at this point, refer back to your original estimate. 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.

Estimate and multiply decimals anchor chart 1. first round your num bers and find a product as estimation. 4.4 x 2.9 4 x 3 = 12 2. multply the numbers without the decimal points. 4.4 x2.9 396 840 1236 3. check the extimation and put the decimal point in a reasonable place. estimation: 12 product: 1236 so, answer = 12.36 4. double check the place. Type of problems. the student is shown the grid and the problem and must write the answer. the student is shown the grid and must write the problem and the answer. the student is shown the problem and must fill in the grid and write the answer.
