Year 7 Spring Term Learning Objectives
Handling Data 6
Number 12
All should be able to
Solve a problem by representing, extracting and interpreting data in tables, graphs, charts and diagrams. Solve problems by representing data in a bar chart and line graph.
Most should be able to
Given a problem that can be addressed by statistical methods, suggest possible answers. Decide which data would be relevant to an enquiry and possible sources. Plan how to collect and organise small sets of data; design a data collection sheet or questionnaire to use in a simple survey; construct frequency tables for discrete data, grouped where appropriate in equal class intervals.
Collect small sets of data from surveys and experiments, as planned.
Construct, on paper and using ICT, graphs and diagrams to represent data, including: -bar-line graphs; -frequency diagrams for grouped discrete data;
use ICT to generate pie charts. Interpret diagrams and graphs (including pie charts), and draw simple conclusions based on the shape of graphs.
Solve word problems and investigate in a range of contexts: handling data.
Some should be able to
Decide the degree of accuracy needed for the data.
Plan how to collect the data, including sample size; construct frequency tables with given equal class intervals for sets of continuous data.
Construct on paper and using ICT:
- pie charts for categorical data;
- simple line graphs for time series.
Understand and use the relationships between the four operations, and the principles (not the names) of the arithmetic laws.
Know multiplication facts up to 10 10. Add several numbers. Use doubling and halving. Partition to multiply mentally TU U.
Extend written methods to:
-HTU U and U.t U; -TU TU; -HTU ÷ U. Divide £.p by a two-digit number to give £.p. Round up or down after division, depending on the context.
Round positive whole numbers to the nearest 10, 100 or 1000 and decimals to the nearest whole number or one decimal place. Understand addition, subtraction, multiplication and division as they apply to whole numbers and decimals; know how to use the laws of arithmetic and inverse operations. Know and use the order of operations, including brackets.
Consolidate and extend mental methods of calculation to include decimals, fractions and percentages, accompanied where appropriate by suitable jottings; solve simple word problems mentally. Make and justify estimates and approximations of calculations. Multiply and divide three-digit by two-digit whole numbers; extend to multiplying and dividing decimals with one or two places by single-digit whole numbers.
Round positive numbers to any given power of 10; round decimals to the nearest whole number or to one or two decimal places. Recall products such as 0.7 and 6, and 0.03 and 8.
Multiply and divide integers and decimals including by decimals such as 0.6 and 0.06; understand where to position the decimal point by considering equivalent calculations.
