Mathematics Mastery

Summary

This FREE unit builds on the work completed in Unit 1 with integers, by extending into decimal values. Initially place value is explored and decimal numbers compared and ordered. The four mathematical operations are considered in the context of decimals and consolidated through intelligent practice. The impact of multiplying and dividing by powers of 10 is explored and place value is used to solve reasoning problems. Techniques with rounding numbers, significant figures and decimal places are developed and the use of approximations to support problems is considered. The work on approximations continues by developing the use of inequalities to express error intervals for rounded and truncated numbers. Contextualised problems help develop a range of written methods to multiply and divide decimal numbers.
