Algernon thinks of a number and doubles it. He then adds 9. The answer comes to 17. What was the number that Algernon first thought of?100014Well done! You just solved te equation 2x + 9 = 171100113Nope, you need to subtract the 9 instead of adding it0018Nope, you need to halve the number after you have subtracted the 90018 1/2Nope, you need to subtract the 9 before halving001What is 50 x 300?1000115 000Well done! Did you find a quicker way of doing it than the long multiplication route? If not, then you might want to have a look at some of the quicker methods.110011 500Nope, check the number of zeros001150 000Nope, check the number of zeros001250Nope, its multiplying, not subtracting001What is the difference between 5000 and 47 ?100014 953Well done! did you use a quick method (e.g. 50 off 5000 then add 3 back) or the full crossing off the top method?110015 047Nope, the word 'difference' means subtract so that the answer comes out positive001235 000Nope, the word 'difference' means subtract so that the answer comes out positive001One is a number in the thousands, the other is only in the tensNope, in Maths the word difference means to subtract, not to compare the numbers and talk about them.001How many kilograms are there in 7 000 grammes?100017 KgWell done.110010.007 KgNope, you need to divide by 1000 not a million0010.7 KgNope, you need to divide by 1000 not ten thousand00170 KgNope, you need to divide by 1000 not a hundred001Evadne thinks of a number and multiplies it by three. Then she subtracts four. The answer comes to 11. What was the number that Evadne thought of?100015Well done! You solved the equation 3x - 4 = 11110012 1/3Nope, you have to add the 4 back on not subtract it00115Nope, you forgot to divide by 30013 2/3Nope, you need to add the 4 before dividing by 3001What is 14 + 2067 + 934 ?100013015Well done!110013005Oops, I think you dropped a carry in the tens column0012905Oops, I think you dropped a carry in the hundreds column0012015The answer is one thousand too far out, check the final carry!001Subtract twelve thousand and forty seven from ninety two thousand, six hundred and fifteen1000180 568Well done!1100180 558Nope, check the crossing off in the 10s column00180 658Nope, check the crossing off in the 100s column00190 568Nope, check the final column! The answer is impossible001Find how many times 45 fits inside 360100018Well done, did you use a long division method or did you group the 45 into 90 and then recognise that there are four groups of two in 360?110014Nope, you recognised that 90 goes into 360 four times, but forgot to double up the number00116 200Nope, 'fits inside' means divide not multiply001315Nope, 'fits inside' means divide not subtract001Find the remainder when you divide 12 096 by 17100019Well done! The full answer to the division sum is 702 r 9110017Nope, check the last bit of the division again0018Nope, check the last bit of the division again001No remainderNope, something has gone wrong!0012042 x 15 = 1000130 630Well done! Did you use the long multiplication method or did you use a short cut method like do 2042 x 100 then add half as much again1100112 252Nope, I think that you forgot to add a zero when you multiplied by the 1 in 15.00130 360Nope, looks like you transposed the 3 and 6 in the hundreds and tens place00112 522Nope, looks like you forgot to put a zero down when you multiplied by the 1 in 15 and that you got two of the digits the wrong way round!001What is 500 less 4071000193Well done! Did you use a quick method like call it 100 then take another 7 off?1100197Nope, check again, you misread the numbers a bit I think001107Nope, check again, you misread the numbers a bit I think001103Nope, check again, you misread the numbers a bit I think001What is the largest number you can make from the digits 0, 2, 7, 3, 9, 5 ?10001975 320Well done, largest digits in the highest value places!11001023 579Nope, you have got the digits exactly the wrong way round!00126Nope, its not about adding up! The idea is to end up with a 6 digit number...00197 532Nope, the digits are in the right order, but you forgot to put the zero on the end!001What is forty two million, six hundred and nine thousand, four hundred and sixteen written as figures...1000142 609 416Well done!110014 269 416Nope, you have missed out a zero. Look carefully at the number of hundreds of thousands, tens of thousands and thousands...00142 000 000 then 609 thousands, and then 416Nope, its all one large number.0014 260 940 016Nope, you have too many digits, you need to think about 'four hundred and 16' as 416...001001Find the product of 15, 25 and 10.100013750Well done, product means multiply all the numbers together1100150Nope, product does not mean add up, it means multiply00110Nope, 'product' does not mean difference, it means multiply0015Nope, 'product' does not mean factor, it means multiply001Find the sum of 25, 35 and 201000180Well done, you added all the numbers which is what 'sum' means in maths110015Nope, nothing to do with factors!00117 500Nope, sum does not mean multiply, it means add up00110Nope, 'sum' means to add001A dress costs £14.99.

He is using four dressings a day. How many days supply does he have?1000172Well done! Did you multiply up then divide or did you divide by 4 first?11001288Nope, that is the total number of , you need to divide by 4 to get the number of days0016Nope, you forgot to multiply by the number of dressings by the number of packets001144Nope, I think you divided by too much somewhere001What is 16 400 less 14 923 ?100011 477Well done! I could not think of any easy ways for doing this110011 577Nope, you need to check the crossing off in the hundreds column0011 486Nope, you need to check the crossings off in the last two columns0011 747Nope, looks like youve mixed up the numbers001How many centimetres in three and a half metres?10001350Well done!110013 500Nope, there are 100 centimetres in a metre0010.035Nope, centimetres are smaller than metres!00135Nope, there are 100 centimetres in a metre00112 really good tomatoes cost £1.80.
