Presentation Transcript

  1. Maths • Year 3 • count from 0 in multiples of 4, 8, 50 and 100; find 10 or 100 more or less than a given number • recognise the place value of each digit in a three-digit number (hundreds, tens, ones) • compare and order numbers up to 1000 • identify, represent and estimate numbers using different representations • read and write numbers up to 1000 in numerals and in words • solve number problems and practical problems involving these ideas.

  2. Maths • Year 4 • count in multiples of 6, 7, 9, 25 and 1000 • find 1000 more or less than a given number • count backwards through zero to include negative numbers • recognise the place value of each digit in a four-digit number (thousands, hundreds, tens, and ones) • order and compare numbers beyond 1000 • identify, represent and estimate numbers using different representations • round any number to the nearest 10, 100 or 1000 • solve number and practical problems that involve all of the above and with increasingly large positive numbers • read Roman numerals to 100 (I to C) and know that over time, the numeral system changed to include the concept of zero and place value.

  3. Four Operations

  4. Addition Using a 100 square Partitioning the numbers 34 + 26 = 60 34 + 20 = 54 54 + 6 = 60

  5. Addition Using an empty number line

  6. Addition Expanded Column Method

  7. Subtraction Using a 100 square 76 – 24 = 52 76 – 20 = 56 56 – 4 = 52

  8. Subtraction Using an empty number line Numicon and practical resources can be used to support this

  9. Subtraction Finding the difference Numicon and practical resources can be used to support this

  10. Subtraction Partitioning and Decomposition

  11. Multiplication Repeated Addition 5 + 5 + 5 + 5 = 20 6 + 6 + 6 + 6 = 24

  12. Multiplication Drawing Arrays 3 + 3 + 3 = 9 3 “lots of” 3 = 9 3 x 3 = 9 5 + 5 + 5 = 15 3 “lots of” 5 = 15 3 x 5 = 15

  13. Multiplication Arrays in the environment Children can find arrays all around them.

  14. Multiplication Partitioning 38 x 5 = (30 x 5) + (8 x 5) 150 + 40 190

  15. Multiplication Grid Method 38 x 5 = 150 + 40 = 190

  16. Multiplication Grid Method 38 x 25 = 600 + 160 + 150 + 40 = 950

  17. Division Sharing Share 12 cookies between 4 people… 12 ÷ 4 = 3

  18. Division As grouping Put 12 people into 6 groups… 12 ÷ 6 = 2

  19. Division Repeated Subtraction 50 ÷ 5 = 50 – 5 -5 -5 -5 -5 -5 -5 -5 -5 -5 How many jumps?

  20. Division Dividing with remainders Can we take away another jump of 4?

  21. Division Rounding up or rounding down? 13 children are going sailing. 4 children can fit in a boat. How many boats will they need?

  22. Division Chunking
