The Sigma Workbook **'AS 1.1 - Numeric Reasoning'** is a write-on student workbook covering the mathematics students must understand to gain *Achieved*, *Merit*, or *Excellence* in the internally assessed Mathematics NCEA Achievement Standard 1.1 – *'Apply numeric reasoning in solving problems'* (AS 91026).

In this workbook students will find **clear explanations** and **detailed worked examples** showing the step-by-step processes that will be needed to solve each type of problem, these are followed by a large number of practice **exercises **and** problems **of increasing difficulty. At the end of the workbook there are two **Achievement Standard Test****s**. Candidates should use these to evaluate their strengths and weaknesses before the internal assessment.

A full set of **answers** is included, which acts as a guide to structuring quality answers. An abbreviated version of the Achievement Criteria and Explanatory Notes of the Achievement Standard itself complete the resource.

**Topics Covered in this Workbook Include** :

**Multiples, Factors & Primes****Integers, Powers and Roots****Number Problems****Decimals****Estimating****Rounding and Accuracy****Calculator Skills****Standard Form****Fractions, Decimals and Percentages****Fraction Arithmetic****Working With Percentages****Ratio****Ratio Tables****Inverse Relationships****Mixed Problems****Financial Literacy****Growth and Decline**

The Sigma Workbook **'AS 1.1 Numeric Reasoning' **is best bought before the standard is taught at school and used throughout this time as a classroom and homework resource. Alternatively, the workbook would make an excellent independent study resource in the lead-up to the internal assessment of Achievement Standard 1.1.
