This six-part lesson is a great addition to any number system lesson. Students will develop a greater understanding of how to add and subtract fractions and decimals. The different parts of this lesson include the following:
*Problem of the Day: Students will begin class by taking a few minutes to answer the problem of the day. Students can write their responses in a notebook, on a loose leaf sheet of paper or on the papers provided. After a few minutes, have students check the work of another classmate, or they can check their own.
*Notes on Adding/Subtracting Fractions + Decimals: Work together as a class to complete the guided notes on fractions and decimals. Students will learn the various steps necessary to solve addition and subtraction problems involving fractions and decimals. Examples problems are also included.
*Adding and Subtracting Fractions Trail: Cut out each problem. Place the problems around the room (sticky tack to the wall, put on desk tops, etc.). I would suggest putting the problems in alphabetical order, but it is not required. To begin, start with any of the 16 problems. Solve the addition/subtraction problem on the bottom of the card. Look for the solution on the top of another card around the room. This will tell students which problem is next in line. Students will continue working until they get back to where they started.
*Decimal Maze Activity: Students will begin with the ‘start’ problem. The answer to the first problem will lead them to the next problem. They will continue solving problems until they reach the ‘end’ section. If they happen to make a mistake, they will need to go back to the beginning and check again.
*Adding and Subtracting Fraction + Decimal Practice Worksheet: Students will need to complete the practice sheet on adding and subtracting fractions and decimals. This can be given as an individual assignment or students could work with a partner or in a group.
*Exit Slip: In the final minutes of class, have student complete their exit slip. This can be completed in a worksheet, on a loose leaf sheet of paper or on the papers provided. This is a great way to assess the level of understanding for each student in the class.
