This short video and interactive assessment activity is designed to teach fifth graders about adding fractions with different denominators.
The math learning center is an app and online platform that allows students to use manipulatives virtually. In this activity, students will use virtual manipulatives to add fractions with unlike denominators
This short video and interactive assessment activity is designed to teach fifth graders about adding mixed numbers with common denominators.
This problem simply asks students to add the tenths and hundredths together.
This undergraduate level course follows Algebra I. Topics include group representations, rings, ideals, fields, polynomial rings, modules, factorization, integers in quadratic number fields, field extensions, and Galois theory.
This Nrich problem follows on from Twisting and Turning and More Twisting and Turning and offers students the opportunity to explore sequences of fractions, make generalizations, and prove conjectures. The rope trick in the first problem offers a moment of surprise when the rope becomes untangled, and this prompts curious students to want to explain what is going on. This third problem in the sequence ties up all the loose ends still remaining.
This Nrich problem embeds adding and subtracting fractions into a bigger problem to increase interest.
This Nrich problem involves complicated reasoning about fractions that challenges children's understandings of the concepts involved. It is a good example of how fractions relate to multiplication and division.
Create your own shapes using colorful blocks and explore the relationship between perimeter and area. Compare the area and perimeter of two shapes side-by-side. Challenge yourself in the game screen to build shapes or find the area of funky figures. Try to collect lots of stars!
Remember your multiplication tables? ... me neither. Brush up on your multiplication, division, and factoring skills with this exciting game. No calculators allowed! The students will be given mutiplication and division problems which they must answer. They also have the option of being given a number then stating the factors of how that number was attained using either multiplication or division.
This word problem requires students to use fractions to solve it.
The purpose of this task is to provide students with a concrete situation they can model by dividing a whole number by a unit fraction.
This Nrich problem requires some simple knowledge of fractions and multiples and demands some strategic thinking. It may offer a good opportunity to compare methods between students - there isn't just one route to the solution. Note that there is no need to use algebra in this problem.
This Nrich problem requires a sound understanding of the relationship between part and whole. It could be used as part of a lesson on finding fractions of numbers and quantities.
This task requries students to think about division by fractons.
This Nrich problem can be used to introduce learning about percentage increases and decreases.
This lesson reviews how to change an improper fraction to a mixed number.
In this video segment from Cyberchase, the CyberSquad must locate a crystal with the highest fraction of orange color.
In this Nrich problem students build on their existing knowledge of proportions to build a function in an engaging context.
In this task using a number line, students must partition the interval between 0 and 1 into eighths.
