**Welcome** to Week 4 of my blog aimed at the 11+ in Buckinghamshire. This week, we look at Missing Letters - a type of Verbal Reasoning - and I give you access to exclusive Missing Letters material. We will also look at Number Lines in Maths. I have checked all clips so that you know they are right for the 11+.

**Maths**

**Number Lines **

Number lines can go up or down by whole numbers like the one pictured above.

Here's a clip.

If you struggle to understand negative numbers, think about the way numbers work on a thermometer, and how the temperature can go from zero to -1, -2 etc.

Practise 10 questions on IXL.

Remember, one section, ten questions, each day

Let's pop over to the interactive number line on the Maths is Fun website. You need to go to the webpage for it to work. Do questions 1-8.

**Number Lines and Decimals**

Number lines can deal in smaller units than whole numbers; number lines can go in-between 1 and 2; think of the millimetres in-between each centimetre on a ruler.

**Click** on the Zoomable Numberline, **shift-click** to zoom out. Click at left or right to scroll.

**More videos and practice on number lines.**

The screen shot below is the first of seven video tutorials. Do all sections in the left hand column. When the first section finishes it will go back to the home page, so scroll down to the next session, and the next until you have done all 7.

So to recap, a number line can go from one whole number to another, or in-between whole numbers.

Practice on IXL

Now some games, only one is pictured but play all four.

**Still haven't learnt your times tables properly?**

http://www.free-training-tutorial.com/times-tables-games.html

Prime numbers only have 2 factors, 1 and itself. Primes only come up in the 1 times table. Learn these primes for next week: 2, 3, 5, 7, 11

**Verbal Reasoning**

**Find the Missing Letter** that ends one word and starts the second word of each pair. One letter must work for both pairs.

**Example:**

**min (?) ag sea (?) hem Missing Letter is t**

**min (t) ag sea (t) hem**

to (?) es ke (?) acht

win (?) oe fin (?) eer

ma (?) art lim (?) each

clas (?) eat bu (?) and

hom (?) ast wak (?) arly

was (?) ere wes (?) orn

cloc (?) ey win (?) ind

bes (?) hem nes (?) ime

lam (?) ink si (?) ouch

lim (?) ow com (?) ring

mic (?) nd us (?) gg

fil (?) ice wil (?) end

TIP: If you get a bit stuck, go through the alphabet, IN ORDER, and try each letter on the first word, then the second, then the third, then the fourth. If it works for all four, you've got the answer! (If you still don't know your alphabet all the way through, look at the graphic in week 1 and learn it.)

Remember that spellings can have different pronunciations.

eg: ow as in glow, and ow as in bow

eg: ea as in breathe, and ea as in breath

Remember c becomes an s sound when combined with e, for example mice, twice

a letter can be doubled, for example, fill.

Still not got the answer? Perhaps you don't know one of the words - take a chance. Mark it with a ? and come back to it when you have finished the others.

Still not got the answer? Read the answers and remember what you missed.
