### NRICH PROBLEM SOLVING KS1 MULTIPLICATION

Use the interactivity to help you find out how many cloves of garlic they might have had. These spinners will give you the tens and unit digits of a number. When will the two be the same height? Age 5 to 11 Clare Green looks at the role of the calculator in the teaching and learning of primary mathematics. Age 5 to 7 Working Backwards at KS1 The lower primary tasks in this collection could each be solved by working backwards. 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.

Doubling Fives live Age 5 to 7 Challenge Level: If you count from 1 to 20 and clap more loudly on the numbers in the two times table, as well as saying those numbers loudly, which numbers will be loud? Once a basic number sense has developed for numbers up to ten, a strong ‘sense of ten’ needs to be developed as a foundation for both place value and mental calculations.

Age 5 to 7 Conjecturing and Generalising at KS1 The tasks in this collection encourage lower primary children to conjecture and generalise. This article for teachers describes how modelling number properties involving multiplication using an array of objects not only allows children to represent their thinking with concrete materials.

Tasks for KS1 children which focus on working systematically. Catrina’s Cards Age 5 to 7 Challenge Level: How could you extend your pattern on the right-hand grid? What was Annie’s secret number? Primary Interactive Resources Age 5 to 11 Details of all primary interactive resources.

Pattern Sniffing Age 5 to 11 This article for primary teachers outlines how we can encourage children to create, identify, extend and explain number patterns and why being able to do so is useful. Use these head, body and leg pieces to make Robot Monsters which are different heights.
