Unit 5: Number Skills
Overview
In this unit you'll work on some techniques to help you improve your fluency when working with numbers. You'll learn techniques for estimation and approximation, develop a sense of how big or small numbers are and how they compare with each other, and work with divisibility tests, which are ways of quickly finding out if one number divides exactly into another.

Assessment
In this assessment you will be assessed on Criterion D: Applying mathematics in real-life contexts.
MYP maths objectives-Y8,9 D.pdfAssessment Checklist
To do well on this assessment you will need to do the following things:
Use tests of divisibility for 2, 3, 4, 5, 6, 8, 9, and 10.
Express single inequalities on a number line and using symbols such as =, ≠, >, <, ≤, ≥.
Take a real life situation and identify all the necessary elements to perform a good estimate.
Make estimates to calculations by first rounding to one significant figure.
Develop proficiency in a variety of techniques for fast and accurate mental calculations and estimating answers to calculations.
Explain all the assumptions and factors that impact the solution.
Round sensibly (decimal place, significant figures) and explain why the chosen degree of accuracy is appropriate.
Performs calculations and estimates that enable you to arrive at a sensible solution that takes into account all of the necessary elements.
End of Unit Review
To support your revision, take a look at the following tasks:
Skills based practice on Dr Frost Maths - click here to check how well you have understood the learning objectives of this unit. You are encouraged to watch the relevant video and practise any skill that you find challenging.
Practice assessment - this is particularly focused on ensuring you have understood i) the statement of inquiry, key and related concepts in relation to the unit, ii) the assessment objective/rubric, iii) key command terms required to understand the assessment and iv) ATL skills you have developed over the unit. Make a copy of and attempt the practice assessment below (suggested answers here):

Make a copy of the document below and follow the following steps for your reflection:
During the Unit
At the beginning of the unit, use the traffic light system to rate how confident you are of the learning objectives. This will help you identify what areas you need to focus on in your lessons and self-study.
Add to the "What key skills have I learnt in the unit?" box key takeaways from your lessons and self-study. You may want use this as notes at the end of each lesson.
Add to the "What key skills do I still need to work on?" box key things that you still need further practice. Make sure you include resources like videos from DrFrostMaths, CorbettMaths, MyiMaths and Eedi etc.
At the end of the unit and prior to the assessment, use the traffic light system to rate how confident you are of the learning objectives. This will help you identify what areas you need to work on for your assessment.
After the assessment
Use the second part of the document to reflect on your assessment:
Add to the "What went well?" box a reflection of the positives. Make sure this is a reflection on the mathematics, not your effort.
Add to the "What do I need to improve on?" box reflection additional things you need to do to address the gaps of knowledge shown in the assessment. Be specific about how you can address the problems. You should start with “I need to… ”
Copy and paste what you wrote in the two boxes onto your student portfolio as part of your reflection for your target.
Upload your reflection document onto your student portfolio as evidence for your reflection.
