This Nrich problem uses the context of sports training to offer opportunities for learners to explore division and/or multiplication. Pupils will be required to consider the relationships between multiplication, division and fractions, which will help reveal their level of understanding.

Young children live in a world of activity, exploration, creation, singing, talk and play.  As they move, sing, explore new ideas, make stuff, talk endlessly about what they are doing, and repeat songs and poems over and over again, primary children are learning.  EL Education has created a rich and academically challenging curriculum with these needs of primary learners at its core.  The K-2 curriculum offers two hours per day of content-based literacy (module lessons and K-2 Labs) plus one hour of structured phonics (K-2 Reading Foundations Skills Block). All together, these three hours of curriculum are considered comprehensive, meaning that they explicitly teach and formally assess all strands and standards of the Common Core English language arts (ELA) standards for each grade level.

This is the first Nrich problem in a set of three linked activities. Egyptian Fractions and The Greedy Algorithm follow on.

It's often difficult to find interesting contexts to consolidate addition and subtraction of fractions. This problem offers that, whilst also requiring students to develop and analyze different strategies and explain their findings.

The Literacy Design Collaborative (LDC) provides a curriculum alignment system that helps teachers deliver standards-driven assignments in which students write in response to reading in discipline-specific ways supported by backwards-designed instruction.

LDC tools and learning experiences help teachers and schools meet the challenges of: (1) increasing the rigor of assignments, lessons, and units by becoming truly standards-driven, (2) increasing teachers' knowledge and expertise around instructional planning, and (3) radically changing the expectations schools and teachers have for their students' ability to read and write with depth and breadth—in other words, to be truly college and career ready.

The LDC CoreTools platform includes: (1) a free Curriculum Library that includes nationally-validated tasks and instructional plans that can be modified to meet any teacher's needs; (2) template-driven task and instructional plan editing tools that can be used collaboratively; (3) student-work rubrics and a curriculum-alignment rubric; (4) free professional learning experiences; (5) premium professional learning experiences, resources, and analytics.

This Nrich activity encourages students to notice and wonder and to engage in mathematical discussions. Students then use graphs to represent the situations.

This Nrich problem encourages children to work together to develop a method for finding a solution which will always work. It will also help to reinforce understanding of odd and even numbers.

This is an opportunity for pupils to set up their own models using a spreadsheet and investigate what happens when they change variables such as interest, inflation rates and how much is spent each year. Investigating how a small change in interest rates can affect the total income over different time periods can be enlightening. Investigating the impact of spending large amounts of money up-front can also provide valuable insights.

In this Nrich activity, students use manipulatives to investigate triangles. They are asked to construct possible triangles and to search for an impossible combination.

This Nrich activity is an unusual context in which pupils can consolidate recognizing, finding, naming and writing fractions. The rich environment also gives them the opportunity to identify, name and write equivalent fractions of a given fraction, represented visually as a chain. Furthermore, learners will be adding and subtracting fractions with the same denominators and denominators which are multiples of the same number.

Welcome to the MOOSE platform! MOOSE is an acronym that stands for Maine Online Opportunities for Sustained Education. This website contains a learning library of assorted project-based learning experiences. Modules are self-paced and offer variety and choice in activities and topics. Search for a module by a specific grade span, subject, or topic, or simply choose something that interests and excites you to get started.

Sign Up is OPTIONAL! This site is free and open to use. Login is used only to keep track of your progress within modules.

To enhance access to anytime, anywhere learning options and resources for educators, students and their families, the Maine Department of Education, in collaboration with curriculum coordinators, Maine educational community organizations, museums, learning centers, and Maine educators, is creating a library of learning modules that are aligned to Maine’s Learning Results.

This problem gives work on percentages in an interesting and challenging way. It also gives you an opportunity to discuss different ways of estimating and therefore shows learners how expressions which look very different can give very close answers.

This Nrich problem brings in doubling, halves and quarters in a very practical way using rods made from interlocking cubes. It gives children a practical context in which to explore simple multiplying and dividing, even if these particular terms are not used explicitly. It can provide a very useful context for introducing and using the vocabulary of halves and quarters.

This Nrich problem encourages children to use counting-on techniques, but offers you an opportunity to introduce them to the idea of multiples.

This Nrich game can be played to improve students' recognition of equivalent fractions, decimals and percentages.

Students sort and classify triangles based on similarities. Students are asked to discuss their decisions in this Nrich activity.

In this Nrich problem students evaluate percentages in the real world situation of an election.

All work on probability is based on ideas of randomness, an idea which has precise mathematical meaning, while being informally used in everyday life. This Nrich activity will lead to discussions of tricky ideas should challenge students' understanding.

This activity from Nrich mathematics encourages students to explore combinations and patterns systematically.

This Nrich problem gives a clear context in which fractions, ratio and proportion can be investigated. When using the interactivity, students can develop strategies for comparing fractions or ratios while thinking about which strategies are most useful for different cases.
