These presentations by Monica Yuskaitis are particularly good. In this one, she shows viewers how to deal with subtracting fractions that have unlike denominator, no small task! This is a tricky process, and this PowerPoint takes young mathematicians through in clear and logical steps. Some practice problems are available at the end of the slide show.
Here is a fabulous instructional activity on subtracting decimals with different numbers of decimal places. There are teacher-led activities for learners to engage in, including, modeling decimal subtraction through decimal squares, looking at place value, seeing patterns in decimal numbers, and finding decimal values on a number line. Then, pupils pair off and play an interactive online game that further reinforces the concepts being taught. Finally, each pupil completes a series of worksheets that are embedded in the plan to gain further practice. An outstanding math lesson plan which should lead to meaningful learning.
Here is an excellent lesson plan on solving subtraction word problems using fractions and mixed numbers. Learners complete three activities that will help them to explore and better-understand the world of mixed numbers. Fraction bars are used as a manipulative, and the activities are all meant to be done as group activities. These lesson plans are extremely well-written.
According to Sal, there are two ways to subtract mixed numbers. One can turn both mixed numbers into improper fractions, or one can subtract the whole number parts and then the fraction parts. Sal shows the step-by-step process to subtract mixed numbers by subtracting the whole numbers first and then the fraction portions last.
Subtracting fractions with unlike denominators can be overwhelming, but in this task, 5th graders work systematically to break down the procedure through three questions. The first two questions ask for pictures to be drawn along with evaluating the subtraction sentences to illustrate why finding a common denominator is important. The third and final question allows for subtraction of an improper fractions without pictures. The activity includes a commentary and a solution page that replaces a traditional lesson plan and provides valuable insight for teachers in order to smoothly implement the lesson in the classroom.
Second graders practice subtracting numbers with regrouping. In this subtraction lesson, 2nd graders participate in a subtraction drill and solve a short subtraction word problem. Students then use bundles of straws to demonstrate how to regroup subtraction problems. Students use manipulatives, such as the straws and illustrations, to solve several subtraction problems.
Fourth graders demonstrate how to subtract five digit numbers. In this subtraction computation lesson, 4th graders review how to find the difference using regrouping. Students then read a subtraction word problem involving money and go through the steps of subtracting five digit numbers in order to find the difference. Students discuss the steps in subtracting five digit numbers and practice several problems independently.
Do your second and third graders need more subtraction practice? Use a worksheet to help them master their subtraction skills with two digit numbers. The first section involves straightforward subtraction problems, while the second section includes money symbols for your mathematicians to bring into their answers. The problems in the third section are written out for them to solve.
