In this lesson plan, students will learn about decimal addition and subtraction and their real life applications. through artistic, interactive guided notes, check for understanding, a doodle and color by number activity, and a maze worksheet, students will gain a comprehensive understanding of adding and subtracting decimals. the guided notes. How to add and subtract decimals. in order to add or subtract decimals: make sure each number has a decimal point and write any 0. 0 \bf {0} 0 placeholders that are required. stack the numbers, ensuring that the decimal points line up. use the standard algorithm for addition subtraction, ensuring the decimal point is also written in the answer.
To add decimals, follow these steps: write down the numbers, one under the other, with the decimal points lined up. put in zeros so the numbers have the same length ( see below for why that is ok) then add, using column addition, remembering to put the decimal point in the answer. Idea 2: money math. real life applications are a great way to connect decimals with practical scenarios. money math is an engaging hands on activity to use when you teach adding and subtracting decimals. this will demonstrate how adding and subtracting decimals can be applied in a monetary context. The addition of decimals involves the following steps: step 1: the numbers are first padded with zero depending upon the maximum digits present after the decimal for any of the numbers. step 2: the numbers are lined up vertically along with each other. step 3: finally, add the decimal numbers similar to integers and place the decimal point. Key learning points. in this lesson, we will solve addition and subtraction problems with decimals and generate our own word problems to suit equations. we will develop our understanding of decimal problem solving through bar models and a variety of real life contexts. this content is made available by oak national academy limited and its.
