Understanding and Using Place Value Level 4 standards to be achieved: Read, write, order and round large numbers and numbers with up to 3 decimal places Understand the effect of multiplying and dividing numbers by 10, 100 and 1000 Use their understanding of place value to calculate accurately and solve problems For children to attain level 4, teach them how to: find the value of each digit in large numbers and decimals order a set of numbers by identifying significant digits position numbers on a number line round whole numbers to the nearest ten, hundred or thousand round decimal numbers to the nearest whole number use rounding to find an approximate answer before tackling tricky calculations multiply and divide whole numbers by 10, 100 and 1000 use a known fact to answer linked decimal facts create and continue number sequences involving decimal numbers interpret decimal numbers in the context of measures such as money and length add and subtract numbers with up to 2 places of decimals use the value of digits to explain the steps in calculation methods or problems Make sure that: children regularly use partially-numbered and blank you use models such as place number lines as part of daily oral and mental work value charts or grids to teach children about place value. Watch for children who believe you reinforce decimal place value that the column to the left of using visual models such as bead thousands represents millions. strings or base 10 apparatus and using Stress that the value of each contexts such as length and money column gets ten times bigger as you move to the left children have regular opportunities to children describe the value of children do not describe their methods decimal digits using the language describe the effect of solving calculations of both decimals and fractions of multiplying by and problems involving e.g. ‘nought point nought two’ 10 as ‘adding a decimals to each other and ‘two hundredths’ nought’ and you.

Reading scales Level 4 standards to be achieved: Read and interpret scales presented in different contexts and orientations. Scales cover various ranges, not always starting at 0, and may or may not include units Read values from scales that have numbered and unnumbered intervals Use scales to measure length, width and capacity accurately to answer questions and solve problems Interpret scales on graphs and charts and use readings to answer questions and solve problems For children to attain level 4, teach them how to: work out the size of each interval, count along the scale to check and label marks recognise how the value of each interval changes when the start/end labels change identify points between two marks and estimate their value read values from scales that are horizontal, vertical or circular as on a clock face interpret scales on graphs and charts, annotating the scale to support accuracy use measuring equipment accurately in the context of length, weight and capacity use their readings to calculate differences and solve problems involving scales use the relationship between units of measure to convert units where appropriate Make sure that: scales are displayed and accessible so that children are taught to identify children can handle and use them regularly where a scale starts and ends and how to use division to find what the interval size you regularly use scales as part of represents your daily oral and mental work children are expected children have a strategy to check children understand to annotate scales and estimated values by counting up the link between write in missing values and down the intervals number lines and on unnumbered marks scales. Count up and down scales, children use scales in different orientations. Show including using them how scales can be rotated if this is helpful alternative units, for example: children have regular opportunities to solve 0g, 100g, 200g… problems that involve reading scales.
