Estimating the answer to a calculation can be a good way to check your work. Identify why it is possible to solve some calculations mentally; explain the clues they looked for and then solve it e.g. Created: Dec 7, 2018| Updated: Jul 2, 2019, This is a handy little resource to generate worksheets for the Year 5 addition and subtraction objective: use rounding to check answers to calculations and determine, in the context of a problem, levels of accuracy, The resource includes 5 worksheets for practising this objective and the accompanying answer sheets (where applicable). Main Lesson: - To use rounding to check answers to calculations (Year 5 Year 6) - To use the 4 operations, including formal written methods, applied to integers and decimals, (KS3) This lesson consists of: A Starter consisting of a series of progressively harder addition, subtraction, multiplication and division calculations. Estimating answers to harder calculations. Learners could to construct a multiplication (subtraction, division) question which they think others will have trouble estimating. Tes Global Ltd is This is a handy little resource to generate worksheets for the Year 5 addition and subtraction objective: use rounding to check answers to calculations and determine, in the context of a problem, levels of accuracy. Estimating the number of hairdressers, piano tuners, newsagents and takeaways in a village, town or city can be discussed and justified before setting out on a statistical hunt for data. An interactive quiz which test your understanding of all the Number and Place Value objectives in the Year 6 curriculum. There are hundreds of potential questions. Write down the calculations that you did. Year 6 Use estimation to check answers to calculations and determine, in the context of a problem, an appropriate degree of accuracy A selection of year 6 maths worksheets that involve using estimation to check answers to calculations and solving problems to an appropriate degree of accuracy. Alternatively, you can use the Interactive Maths Quiz which includes objectives from all strands of the Year 6 curriculum. Statement 6 – Divide proper fractions by whole numbers, Statement 1 – solve problems involving the relative sizes of two quantities where missing values can be found by using integer multiplication and division facts, Statement 2 – solve problems involving the calculation of percentages [for example, of measures, and such as 15% of 360 and use percentages for comparison], Statement 3 – solve problems involving similar shapes where the scale factor is known or can be found, Statement 4 – solve problems involving unequal sharing and grouping using knowledge of fractions and multiples, Statement 1 – solve problems involving the calculation and conversion of units of measure, using decimal notation up to three decimal places where appropriate, Statement 2 – use, read, write and convert between standard units, converting measurements of length, mass, volume and time from a smaller unit of measure to a larger unit, and vice versa, using decimal notation to up to three decimal places, Statement 3 – convert between miles and kilometres, Statement 4 – recognise that shapes with the same areas can have different perimeters and vice versa, Statement 5 – recognise when it is possible to use the formulae for area and volume of shapes, Statement 6 – calculate the area of parallelograms and triangles & Statement 5 – recognise when it is possible to use the formulae for area and volume of shapes, Statement 7 – calculate, estimate and compare volume of cubes and cuboids using standard units, including cubic centimetres (cm3) and cubic metres (m3), and extending to other units [for example, mm3 and km3], Section 1 – draw 2-D shapes using given dimensions and angles, Section 2 – recognise, describe and build simple 3-D shapes including making nets, Section 3 – compare and classify geometric shapes based on their properties and sizes and find unknown angles in any triangles, quadrilaterals, and regular polygons, Section 4 – illustrate and name parts of circle, including radius, diameter and circumference and know that the diameter is twice the radius, Section 5 – recognise angles where they meet at a point, are on a straight line, or are vertically opposite, and find missing angles, Statement 1 – describe positions on the full coordinate grid (all four quadrants), Statement 2 – draw and translate simple shapes on the coordinate plane, and reflect them in the axes, Statement 1 – interpret and construct pie charts and line graphs and use these to solve problems, Statement 2 – calculate and interpret the mean as an average, Statement 2 – generate and describe linear number sequences, Statement 3 – express missing number problems algebraically, Statement 4 – find pairs of numbers that satisfy number sentences involving two unknowns & Statement 5 – enumerate possibilities of combinations of two variables, Statement 1: read, write, order and compare numbers to at least 1 000 000 and determine the value of each digit, Statement 2: count forwards or backwards in steps of powers of 10 for any given number up to 1 000 000.
