Interpret operator symbols correctly in varied contexts List
• • • Interpret operator symbols correctly in varied contexts. List words that mean addition, subtraction, multiplication and division. Multiply by 10 and 100 without calculator, Divide by 10 and 100 without calculator. Count in multiples of 10 and 100 up to 1000. State times tables and squares to 10 x 10, identify multiples of 10, 50, 100 and 1000. Use operators in practical situations to solve problems. E 2 Interpret x and = in practical situations to solve problems, write signs x and =, list words which mean ‘multiplication’, work out problems including the signs x and =, multiply single-digit whole numbers, use a calculator to check multiplication calculations using whole numbers E 3 Multiply whole numbers without calculator, multiply two digit whole numbers by single digit whole numbers without calculator, use symbols to record calculations, estimate answers to calculations. Count in 10 s and 100 s from any number below 1000. Work out whole number calculations with remainders, divide two digit whole numbers by single digit whole numbers, interpret remainders, use ÷ and = in practical situations, list words that mean division, solve division problems without calculator, check solutions to problems with and without calculator L 1 Multiply whole numbers up to 6 digits by 10 without calculator. Multiply whole numbers up to 5 digits by 100 without calculator. Check calculations without calculator. Times tables up to 10 x 10. Multiples of 10, 50, 100 and 1000. Squares to 10 x 10. Divide whole numbers up to 7 digits by 10 and 100 without calculator. Divide whole numbers up to 7 digits by whole numbers of any value with and without calculator. L 2 Carry out operations within calculations in the correct order.

Why do I need to know this? • Calculate accurately with multiple operators • Tell the difference between positive and negative numbers When will I need to use this? • Working with temperature • Understanding debit and credit in bank accounts • Following instructions • Working with formula, e. g area and perimeter
Revision Questions • 3 +5 x 2 • 6 – 4÷ 2 • What is the temperature difference between 4 and -6? • Which number is three less than -9? • When a calculation has +-, which sign can you use instead?

Addition • Is 4 + 2 the same as 2 + 4? • Remember to keep units, tens and hundreds in line 42 + 49 104 + 51 42 + 49 ____ 104 + 51 ____ 9502 + 829
Subtraction • Is 4 - 2 the same as 2 - 4? • Remember to keep units, tens and hundreds in line 48 - 21 160 - 74 48 - 21 ____ 160 - 74 ____ 7000 - 4320
Multiplication • Is 4 x 2 the same as 2 x 4? • Use the grid method
Division • Is 4 ÷ 2 the same as 2 ÷ 4? • Use the bus stop method 48 ÷ 4 ____ 4|48 120 ÷ 6 _____ 6|120 704 ÷ 3
