# Year 5 Maths Mental-Oral Starters

By Ruth Merttens - 5 Jul 2018

Get your maths lesson going with a bang!

Each term, we provide 48 starters – enough for 4 per week for 12 weeks – plus a set of 12 ‘Fun-Fair Friday’ tests.
Starters are categorised under key mathematical skills – see headings below.
ALL starters in Place value & number, Apply known addition & subtraction facts and Mental addition & subtraction are FREE to download. Others are only available to Friends and School subscribers.
In each download, expect starters further down the list to get slightly harder. Most starters include a couple of quite challenging questions!
Starters with an E at the end of the download filename should be easier, as they revisit skills from Year 4 or from previous Y5 terms.

Place value and number *FREE*
Locating numbers on a line and rounding

Children estimate where to place large numbers and decimal numbers on a landmarked line; also applying their understanding of place value and decimals to compare and order numbers.
They practise interpreting and reading scales for units of measurement.
They round whole numbers to the nearest 100, 1000, 10,000 or 100,000, and decimals to the nearest tenth or whole number.

______________________________________________________________________________________________

Apply known addition and subtraction facts *FREE*
Adding to place value ‘boundary’ numbers, such as the next whole, 100, 1000 and £1. Find totals and differences.

Children apply learned number facts to add to make a given total or recognise pairs with a given difference. They add to the next multiple of 100 or 1000 and apply their understanding of decimals to add to the next whole number and next £1.

Mental strategies adding and subtracting, including money

Children use their understanding of place value to add and subtract multiples of 0.01, 0.1, 10, 100 and 1000 and extend this to add/ subtract amounts of money. They practise mentally adding two numbers choosing an appropriate and effective non-written strategy. They also rehearse mental strategies to find a difference, counting up from the smaller to the larger number.

Times tables
Practise multiplication and division facts

In Autumn, most starters focus on a particular times table – probing both multiplication and division facts, e.g. What is 9 x 12? How many 12s in 108? To make this more challenging, we add some tricky questions outside simple recall of facts - encourage all children to have a go! In Autumn, two starters focus on applying known facts to find answers above the 12th multiple.
In Spring and Summer, expect mixtures of tables, with division facts alongside the multiplications. Questions challenge children to multiply numbers beyond the 12th multiple and by lower multiples of 10.

Autumn: Multiplication and division facts (6) | Beyond the 12th multiple (2)
Spring:  Tables (7)
Summer: Tables (7)

Mental multiplication and division
Multiplying/dividing by 10/100/1000; doubling/halving and using mental strategies

Children rehearse their understanding of place value in relation to multiplication and division by multiplying and dividing by powers of 10. Throughout the year, they practise doubling and halving large numbers and decimals and use these in rehearsing the use of mental multiplication and division strategies. Children also scale numbers up and down by a factor of 4 or 10 in Autumn, and by 4, 5 and 10 in Spring and Summer.
Mental strategies are explored in Spring to x/÷ by 20, 8 and 6, to derive and manipulate remainders and to identify lowest common multiples and highest common factors.

______________________________________________________________________________________________

Fractions
Matching equivalent fractions, considering ‘simplest form’ and exploring improper fractions

Children look carefully at sets of fractions to identify pairs or threes of equivalent fractions, which may include improper fractions, mixed numbers and decimals. Children practise recognising and expressing fractions in their simplest form. Children convert improper fractions to mixed numbers and recognise decimal equivalents.
Calculation of unit/ non-unit fractions of amounts is introduced in Spring and consolidated in Summer.

Telling the time
Identifying analogue and digital times and calculating intervals

In Autumn, children identify and match analogue and digital times, including the use of 24-hour clock. They also calculate intervals between times, again using the 24- hour clock. In Spring and Summer, timetables are used as a real-world stimulus for calculation of durations and intervals.

FUN-FAIR FRIDAY TESTS
Testing children’s basic skills rehearsed in Starters

The tests each have ten questions and are fun to do as children compete not against each other, but against their PB (personal best). Each week, they see where they have got to on the Fun-Fair Height Chart – which rides will they be able to do?
