Year 1 Maths Overview (v2)Our Year 1 Maths learning builds on the foundation set in Reception and is, of course, based on the National Curriculum.  We aim to both support and challenge the children through structured teaching and by reinforcing key concepts with concrete objects and pictorial representations wherever possible.  We believe that all children should be provided with opportunities to work at greater depth and encourage children to really think about their learning by asking questions such as: Why? ... What happens if...? How could you explain that?Here is a summary of the key areas of learning and the 'Big Ideas' that are relevant for each area of study.  Children will be taught core mathematical procedures and skills and will be asked to apply these by solving a variety of problems. The BIG Ideas- The position a digit is placed in a number determines its value.- The language used to name numbers does not always expose the place value, for example the word ‘twelve’   does not make it transparent that the value of this number is ten and two. It is important that children develop   secure understanding of the value of each digit.- Place value is based on unitising: treating a group of things as one ‘unit’. In mathematics, units can be any size,   for example units of 1, 2, 5 and 10 are used in money. In place value units of 1, 10 and 100 are used.The BIG Ideas- Relating numbers to 5 and 10 helps develop knowledge of the number bonds within 20. For example, given 8 + 7,   thinking of 7 as 2 + 5 and adding the 2 to 8 to make 10 and then the 5 to total 15.- Thinking of part whole relationships is helpful in linking addition and subtraction. For example, where the whole   is 6, and 4 and 2 are parts. This means that 4 and 2 together form the whole, which is 6 ... 6 subtract 4 leaves   the  6 subtract 2 leaves the 4.
