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.
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.
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.
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.
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.
In this math worksheet, 3rd graders master subtraction of three digit numbers minus two digits. Students work 100 problems with regrouping in each.
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.
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.
Second graders practice subtracting numbers with regrouping. In this subtraction lesson plan, 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.
Students answer computation questions without paper and pencil. In this subtraction lesson, students solve word problems and complete subtraction exercises.
Learners complete subtraction problems. In this subtraction instructional activity, students review the concept of subtraction with story problems and pictures. They subtract using a number line and practice writing the problem vertically.
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.
Subtraction worksheets can be a useful way for students to practice necessary skills.
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.
Fifth graders solve problems where they subtract and regroup. In this math/subtraction lesson plan, 5th graders solve a warm up problem following problem solving steps. Additionally, students match the number problem to the correct answer.
Second graders regroup to subtract numbers. In this subtraction lesson, 2nd graders see the concept of regrouping through pictures and diagrams. They complete some subtraction problems with numbers up to the ten thousands place.
In this mathematical subtraction worksheet, 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.
In this subtraction worksheet, students practice subtracting three digit numerals. Twenty five problems are listed. Some problems do require regrouping.
In this three-digit minus three-digit subtraction worksheet, students problem solve and calculate the answers to one hundred mathematical equations.
Third graders demonstrate how to subtract numbers with regrouping. In this subtraction computation lesson, 3rd graders review the steps of subtracting with regrouping and read subtraction word problems. Students solve these word problems by subtracting the given numbers. Students continue to practice subtraction with regrouping by solving several problems independently.
