Reportsolutions to puzzles and problems, giving explanations andreasoning orally and in writing, using diagrams and symbols

I can explainhow I solve problems, using diagrams and symbols to helpme

Whatinformation did you use to solve this problem? Why?
Tell me why you chose this way to record your solution to theproblem. Could you have done it differently?
Make up a word problem that could be solved using each calculation:6 5, 30 3, 30 7, 26 19
Sort these problems into those you would do mentally and those youwould do with pencil and paper. Explain your decisions.

Usedecimal notation for tenths and hundredths and partition decimals;relate the notation to money and measurement; position one-placeand two-place decimals on a number line

I can usedecimals when I work with money andmeasurement

Canyou tell me what the digit 7 represents in each of these amounts:2.70, 7.35 m, 0.37, 7.07 m?
Which is larger: 239p or 2.93? Why?
Put these in order: 0.56, 125p, 3.60, 250p, 7p, 5, 205p. Whichis the smallest? How do you know? Which is the largest? How do youknow?
What amount of money comes next: 1.76, 1.86,1.96,...?

Addor subtract mentally pairs of two-digit whole numbers
(e.g. 47+ 58, 91 35)
I can add and subtract mentallypairs of two-digit numbers and find a difference by countingon

Whatstrategies would you use to work out the answers to thesecalculations: 47 58, 91 35? Could you use a different method? How could you checkthat your answer is correct?
The difference between a pair of two-digit numbers is 13. Whatcould the pair of numbers be?
How would you calculate the answer to 93 86? Why would you choose that strategy?

Refineand use efficient written methods to add and subtract two-andthree-digit whole numbers and .p

I can add andsubtract three-digit numbers using a writtenmethod

Whichof these are correct/incorrect? What has this person done wrong?How could you help them to correct it?
How does partitioning help to solve 436 247?
What tips would you give to someone to help them with columnaddition/subtraction?

Recogniseand continue number sequences formed by counting on or back insteps of constant size

I can count onand back in sevens

Counton in sevens from zero. Now count back to zero. This time, count oneight sevens from zero.
Show me seven hops of eight from zero on the number line. Now showme eight hops of seven. What do you notice?

Deriveand recall multiplication facts up to 10 10, the correspondingdivision facts and multiples of numbers to 10 up to the tenthmultiple

I know my tables to 10 10
I can use the multiplicationfacts I know to work out division facts

Theproduct is 40. What two numbers could have been multipliedtogether?
How many multiplication and division facts can you make, using whatyou know about 24 (or 20, 30)? How did you work out the divisionfacts?

Multiplyand divide numbers to 1000 by 10 and then 100 (whole-numberanswers), understanding the effect; relate to scaling up ordown

I can multiplyand divide numbers by 10 or 100 and describe what happens to thedigits

Whatnumber is ten times bigger than 500?
Explain the calculation you would use to change 25 to 2500.
How many tens are there in 200? How many hundreds in 2000?
If 4 6 = 24, what is 40 6 and 400 6? How could you quicklywork out the answers to these calculations: 3 80, 120 4?
The product of two numbers is 2000. What could the two numbersbe?

Developand use written methods to record, support and explainmultiplication and division of two-digit numbers by a one-digitnumber, including division with remainders (e.g. 15 9, 98 6)

I can multiply and divide a two-digit number by a one-digitnumber

Howwould partitioning help you to calculate 27 6?
How does knowing that 10 6 = 60 help you to calculate the answerto 72 6?
Do all divisions have remainders?
Make up some division questions that have no remainder. How did youdo this? Why don't they have a remainder?
Make up some division questions that have a remainder of 1. How didyou do it?

Useknowledge of rounding, number operations and inverses to estimateand check calculations

I can estimateand check the result of a calculation

I can estimate andcheck the result of a calculation

Roughly,what answer do you expect to get? How did you arrive at thatestimate?
Do you expect your answer to be greater or less than your estimate?Why?

Respondappropriately to others in the light of alternative viewpoints

I can explainhow I solved a problem and can decide whether someone else solvedit in a better way

Explainwhat information you used to solve the problem. What stages did yougo through to complete it?
What calculations did you do? Did you draw any diagrams? Why? Didanyone solve the problem in a different way?
Which do you think was the best way to solve the problem?Why?
