This is an excellent visual which encourage students to estimate a point on a number line such as 3.7 then has the option of numbers such as 3.46 and then gives the solution by zooming in – Click here 
Rounding Shopping Bills Project a series of numbers on the board and ask them to do a running total, whilst keeping an accurate answer yourself using a calculator Estimating shopping bills by rounding to the nearest whole number and pairing to make multiples of £10 – give out till receipts with total missing and circulate to see what answers they get.

Ordering Decimals Write down a series of 6 decimal numbers on the board and ask pupils to rank them in order 16 from smallest to largest.  include a clear explanation of their reason. Use this as an opportunity to link with the topic of rounding:
So 0.437, 0.47, 0.5012,
0.52, 0.509
This method highlights the fact that the tenths are the most important value etc...

Ordering Fractions Fractions on a Clothes Line – Click here Fraction Cards
Deal five cards to each player. Set the remainder of the deck face down in the middle of the table as a draw pile. You will play six rounds: · Closest to zero · Closest to 1/4 · Closest to 1/3 · Closest to 1/2 · Closest to one · Closest to two In each round, players choose two cards from their hand to make a fraction that is as close as possible (but not equal) to the target number. Draw two cards to replenish your hand. The player whose fraction is closest to the target collects all the cards played in that round. If there is a tie for closest fraction, the winners split the cards as evenly as they can, leaving any remaining cards on the table as a bonus for the winner of the next round. After the last round, whoever has collected the most cards wins the game.

@NatBanting
The goal was to develop a simple visual that could foster creative thinking around fractions. An unassuming idea, and open disposition, began to open up huge spaces for mathematical action for my students.
The idea is simple, the medium is practical, and the thinking is
rich. This site is a growing cache of materials designed for
classroom teachers. Enjoy, invent, contribute

Multiply and Divide by Powers of 10 Start with the number line 1 to 9 x10 to and write the numbers above, x100 and write above again, /10 then /100 to get
From this we can deduce that 4.3 x 10 must lie between 40 and 50 and equals 43 This links to the work on standard form where we always begin with a number on the blue line. We can also use it to reference problems like 34/10 = 3.4 320/100 etc... 

Standard Form Use this to draw out that you times by 10 each time you move up a row, and always start from the yellow row to give 600 = 6x10x10 = 6x10^{2} and 0.009 = 9 and down 3 rows = 9x10^{3}

Percentages If the world were 100 people is a good introduction to percentages as it requires students to gather data about a wide range of information and then presenting in an appropriate way whilst giving them a secure understanding of the fact that a percentage is out of 100
