Welcome to week 2 of my free interactive 11+ Bucks course! You may be a child reading this on your own, or with a parent, a nanny, or a granddad, whoever – this is for you.
A lot of year 5 children are doing extra work to prepare for the 11+ exam, and if you are in year 5 you need to start too, and now. You need to study Maths, Verbal Reasoning and non Verbal Reasoning, every week, so this blog will be updated every week, just as if you were attending tuition. I am a professional 11+ tutor but I am sharing my weekly notes, tips, and free clips to other people's videos and practice questions, all for free, nada, gratis. Here we go...
Rounding. Why learn to round numbers? Because there is likely to be a question on this in the 11+ exam to get into the Buckinghamshire grammar schools, that's why. Plus rounding is useful for speeding maths up. Speed is essential for the 11+, which is all timed. Here’s a clip to explain further:

Rounding for the 11+ When you know your columns, (see week 1 of this blog,) you are ready to understand rounding. There are some rounding games when you have done your rounding work.
The number mentioned in the question – we will call it Big Bob - can be in the Hundreds, Tens, Units, or Tenths column.
Now look at that number ONE PLACE TO THE RIGHT of Big Bob, and see if it is 5 or over. If it is, Big Bob goes up by 1 number.
Or, if it is 4 or less, we leave Big Bob as he is.
Either way all the numbers after Big Bob change to a nice round 0.
Here's another clip
Round to the nearest whole numbers Practice (right)

Rounding Whole Number: More practice (the explanations in the link below starts with hundred then goes to thousands then to tens, but it's still worth a look.)
Rounding Decimals for the 11+
This is the same as rounding whole numbers, but you do it in the decimal columns. (There are some rounding decimal games when you have finished the work.)
Rounding up from 9 is tricky.
Did you notice in the clip above (after one-and-a-half-minutes) with the example 1.962, the 9 rounded up to a 10? This is important to remember. You can't fit 10/two digits in one column, so only the 0 can remain and the 1 needs to be carried over the next biggest column, so 1 becomes 2.
'Round to the nearest whole number' means round to the units column. So 103.8 becomes 103
'Round to one decimal point' means round to the tenths column. So 103.88 becomes 103.9
Round to the nearest tenth (a clip)
Use Rounding for a question like: Which is smallest? You don't need to work them out exactly, which saves a lot of time.
22 x 8 20 x 10 = 200
0.547 x 80 0.5 x 500 = 250
257 x 0.8 300 x 1 = 300
2470 x 9 2470 x 10 = 24700
Much easier, and the answer is still obvious.
However, if you had two round the same, you do have to work those two out exactly, but that is still quicker than working them all out exactly.
22 x 8 becomes 22 x 10 = 200
247 x 0.8 becomes 22x10 =200
So you need to work those out exactly to find the smallest. ( 247 x 0.8 = 176, and 247 x 0.8 = 197.6)
Remember: All numbers AFTER the number in the column you are rounding to are ‘rounded,’ that is turned into a nice round 0. How to round numbers: this video below is helpful. It begins with the basics, then levels up. You may need to watch it more than once.
More practice and an overview of rounding
Practise on IXL: Remember If you get an answer incorrect, scroll down the page on IXL for tips about how to do better next time. Mistakes are a great learning opportunity: do not waste this.

If you still need to practise your times tables - you need to know them off by heart - here's some more games:
Verbal Reasoning for the 11+ in Bucks Alphabetical order, as in the dictionary
Let's get into the mood by playing a game practicing putting the alphabet in order
The first letter is most significant. (see line one below)
If first letter is the same, then the second letter is the most important (line 2 below)
If the first two letters are the same, the third letter is the most important, and so on.... (line 3 and 4 below)
Look at the words below. The words in blue are not in alphabetical order; the arrow points to the most significant letter.
Can you put them into alphabetical order?
If not, here's a clip to remind you (ks1 level)
Too easy? Try the clip below.
More practice - start at 'medium,' do 'hard' and go on to 'really hard'
Here is some further practice: Put these words into alphabetical order.
But beware, the words might require you to go to the second letter of the first word, then the third letter of the second word, then back to the frist letter of the third word.... let me give you an example...
See what I mean? (Answers at the very end of this blog)
Practice on IXL (You only get 10 questions a day free so do a different IXL exercise each day. Don't worry if you can't fit them all in on one week. You can continue another week.)
Do the same on year 6
Answers to my questions:
- aardvark, abacus, acronym, additive, aerosol
- settle, shoot, strange, swarm, sworn
- recluse, regenerate, remember, revive, revolve
- darling, divine, virtuous
This week's Ten(ish) words
amble (to walk casually) Synonyms: stroll, saunter, dawdle, meander, mosey, ramble, sashay, drift, toddle, wander, gander. Antonyms: jog, trot, sprint, dash, canter.
Draw some doodles of stick figures walking slowly. How are you going to make it clear they are ambling rather than jogging?
Now draw some stick figures sprinting/dashing/jogging.
non-Verbal Reasoning for the 11+ in Bucks
Move a letter from one word to another work, but all words remain real words!
