Adding and Subtracting Fractions
With a pie graph and an infinite blackboard, this video shows how to add, subtract, and simplify fractions. Once he has established the rule, Sal throws the viewer a curve ball with a fraction subtraction problem that results in a negative number.
Fraction - Subtracting Unlike Denominators
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.
Subtraction of Decimals
Here is a fabulous lesson 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.
Subtracting Mixed Numbers
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.
Three-Digit Minus Two-Digit Subtraction
In this math worksheet, 3rd graders master subtraction of three digit numbers minus two digits. Students work 100 problems with regrouping in each.
Finding Common Denominators to Subtract
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.
Solving Problems Involving Subtraction
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.
Subtracting Numbers without Regrouping
Learners subtract four-digit numbers from larger numbers without regrouping. Pupils play games and use manipulatives to practice problem solving. You will find some useful ideas for solidifying subtraction concepts with your math masters.
Subtracting Numbers With Regrouping in the Tens Place
Second graders practice subtracting numbers with regrouping. For 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.
Subtracting 2-digit Numbers Without Regrouping
Learners answer computation questions without paper and pencil. In this subtraction lesson plan, students solve word problems and complete subtraction exercises.
Subtracting 1-digit Numbers without Regrouping
Students complete subtraction problems. In this subtraction lesson, students review the concept of subtraction with story problems and pictures. They subtract using a number line and practice writing the problem vertically.
Subtraction With Regrouping
Fourth graders demonstrate how to subtract five digit numbers. In this subtraction computation lesson plan, 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.
Subtraction worksheets can be a useful way for students to practice necessary skills.
Subtracting Mentally Similar Fractions
Students practice mental subtraction with fractions. Students subtract fractions with like denominators mentally to solve word problems. Students manipulate fraction bars to represent subtraction problems. Students play fraction subtraction games.
Subtracting 3 - to 4- Digit Numbers From 4 - to 5- Digit Numbers with Regrouping in the Thousands
Fifth graders solve problems where they subtract and regroup. In this math/subtraction lesson, 5th graders solve a warm up problem following problem solving steps. Additionally, students match the number problem to the correct answer.
Subtracting Numbers with Regrouping in the Ten Thousands Place
Second graders regroup to subtract numbers. In this subtraction lesson plan, 2nd graders see the concept of regrouping through pictures and diagrams. They complete some subtraction problems with numbers up to the ten thousands place.
Subtraction: Fill in the Gaps 3
In this mathematical subtraction activity, students problem solve eighty subtraction equations by filling in the blanks with numbers that when subtracted from the other given numbers will equal the answer shown.
For this subtraction worksheet, students practice subtracting three digit numerals. Twenty five problems are listed. Some problems do require regrouping.
Three-Digit Minus Three-Digit Subtraction (N)
In this three-digit minus three-digit subtraction activity, students problem solve and calculate the answers to one hundred mathematical equations.
How Do You Subtract a Negative Number from a Positive Number?
Subtracting an integer is as simple as adding the opposite value. Watch this video to see an example of how to change the signs and then add the two integers. Use this as a review after you have taught this valuable skill to your middle school math class.
