Year 7 curriculum Measurement and Chance and Data Measurement Understand the concept of length, area and volume Establish the formulas for areas of rectangles, triangles and parallelograms and use them in problem solving Calculate volumes of rectangular prisms Chance and Data Construct sample spaces for single step experiments with equally likely outcomes Assign probabilities to the outcomes of events and determine probabilities for events Identify and investigate issues involving continuous or large count data collected from primary and secondary sources Construct and compare a range of data displays including stem and leaf plots and dot plots Calculate mean, median, mode and range for sets of data. Interpret these statistics in the context of data Describe and interpret data displays and the relationship between the median and the mean Assumed knowledge: Know how far a mm, cm, m, and km are. Know what mm, cm, m and km refer to. Student’s can multiply whole numbers and decimals. Have some idea of how to use a ruler and measure accurately. Common misconceptions: Not understanding the difference between distance, area and volume. Nut understanding area by itself. Not understanding the concept of volume. That all probabilities need to add to 1. Sample space is all the possible outcomes Key terminology: Distance Area Volume Sample space Probability Favourable outcomes Mean Median Mode Stem and leaf plots Dot plots Outcome of events Key understanding: Distance, Area and Volume represented different quantities All probabilities are between 1 and 0. Key skills: Students at year 7 should be able to understand what length is, and what units we use to measure length in mm, cm, m, km etc. Understand that area is not in one direction. That it is 2 dimensions, and we measure it in cm2 or m2. Volume is the space take up in something such as a coke can- it’s the liquid in the middle. Student should be able to use the formulas A=LxW for a rectangle, A ½ LxW for triangles and A= BxH for parallelograms. Students should be able to explain what a prims is – that is has the same shape on the ends when cut across its length the shape will always bee the same,. Students needs to be able to calculate the Volume of prism’s as well using the formula V=A x H. Students should be able to construct sample spaces for single step experiments with equally likely outcomes, eg Pr{1,2,3,4}. And use formulas to determine probabilities for events. Students should be able to construct and compare a range of data displays including stem and leaf plots and dot plots. Students should be able to calculate mean (average), median (middle number), mode (event that occurs the most) and range(lowest to highest) for sets of data. Students then need to be able to interpret these statistics in the context of data and explain in their own words that the data is showing. Describe and interpret data displays and the relationship between the median and the mean
