# NRICH PROBLEM SOLVING KS1 MULTIPLICATION

Magic Plant Age 5 to 7 Challenge Level: Clapping Times Age 5 to 7 Challenge Level: Choose four of the numbers from 1 to 9 to put in the squares so that the differences between joined squares are odd. Age 5 to 7 Conjecturing and Generalising at KS1 The tasks in this collection encourage lower primary children to conjecture and generalise. Encourage your learners to persevere – there’s often a great sense of achievement when we’ve had to struggle. Number Arrays Age 5 to 11 This article for teachers describes how number arrays can be a useful reprentation for many number concepts. First they were counting in twos.

What Is the Question? Caterpillars Age 5 to 7 Challenge Level: Nim-7 for Two Age 5 to 14 Challenge Level: Share Bears Age 5 to 7 Challenge Level: How will you work out which numbers have been used to create this multiplication square? The upper primary tasks in this collection could each be solved by working backwards.

And pronlem do you know you’ve found them all? Interactives – Lower Primary Age 5 to 7 Try these interactives to improve your skills in a variety of topics. This article for teachers describes how number arrays can be a useful reprentation for many number concepts.

This activity focuses on doubling multiples of five. Your Solutions Age 5 to The lower primary tasks in this collection could each be solved by working backwards. Tasks for KS2 children which focus on working systematically.

Multiplying and Dividing Age 5 to 7 Try these problems, which are all about multiplying and dividing different numbers. Interactives – Lower Primary Age 5 to 7 Try these interactives to improve your skills in a variety of topics.

UGED CRITICAL THINKING

## 107 Matches for age 3 to 5 for basic multiplication facts

Student Solutions Age 5 to Age 5 to 7 Challenge Level: Age 5 to 7 Challenge Level: Generalising Age 5 to 11 These tasks give learners chance to generalise, which involves identifying an underlying structure. Set your own aolving of challenge, practise your table skills and beat your previous best score.

To support this aim, members of the NRICH team work in a wide range of capacities, including providing professional development for teachers wishing to embed rich mathematical tasks into everyday classroom practice.

Student Solutions Age 5 to Arrays, Multiplication and Division Age 5 to 11 This article explores the use of the array to support children’s thinking around multiplication and division. In this article for primary teachers, Lynne McClure outlines what is meant by fluency in the context of number and explains how our selection of NRICH tasks can help. Read the article here.

# Problem-solving Skills :

Can you find a pair of numbers that has four odds between them? Multiplication and Division KS1.

This article multiiplication at how models support mathematical thinking about numbers and the number system. Generic Proof Age 5 to 11 Here we have gathered together tasks which focus on generic proof. Age 5 to 7 Working Backwards at KS1 The lower primary tasks problemm this collection could each be solved by working backwards.

Fractions Unpacked – Starting Points Age 5 to 11 This group of tasks provides a chance for meaningful mathematical discussion about fractions and sharing of current understanding. An article that reminds us about the value and importance of communication in the mathematics classroom.

# Patterns and Sequences KS1 :

Age 5 to 16 By following through the threads of algebraic thinking discussed in this article, we can ensure that children’s mathematical experiences follow a continuous progression. These activities lend themselves to systematic working in the sense that it helps to have an ordered approach. Secret Number Age 5 to 7 Challenge Level: Create a pattern on the left-hand grid.

What different shapes do they make if each part lies in the small squares of a 4 by 4 square?

Activities on the Gattegno Chart Age 5 to 11 In this article, Alf outlines six activities using the Gattegno chart, which help to develop understanding of place value, multiplication and division. Age 5 to 18 Here we describe the essence of a ‘rich’ mathematical task. Using the basic tile, can you make a repeating pattern to decorate our wall?

This article for teachers looks at how teachers can use problems from the NRICH site to help them teach division. Working Systematically at KS1.
