Missing Operations ExerciseEach box represents a missing operation (add, subtract, multiply or divide). What are they? 
This is level 1: numbers up to 10. You will be awarded a trophy if you get at least 9 correct and you do this activity online.
Click the squares between the numbers to select the operations.
Write one of the symbols \( + \,  \, \times \, \div \) in each of the boxes to make the statements correct.
InstructionsTry your best to answer the questions above. Type your answers into the boxes provided leaving no spaces. As you work through the exercise regularly click the "check" button. If you have any wrong answers, do your best to do corrections but if there is anything you don't understand, please ask your teacher for help. When you have got all of the questions correct you may want to print out this page and paste it into your exercise book. If you keep your work in an ePortfolio you could take a screen shot of your answers and paste that into your Maths file.

Comment recorded on the 24 May 'Starter of the Day' page by Ruth Seward, Hagley Park Sports College: "Find the starters wonderful; students enjoy them and often want to use the idea generated by the starter in other parts of the lesson. Keep up the good work" Comment recorded on the 1 February 'Starter of the Day' page by Terry Shaw, Beaulieu Convent School: "Really good site. Lots of good ideas for starters. Use it most of the time in KS3."

❎If you are new to this topic I suggest you try the BIDMAS exercise first in order to become familiar with the 'order of operations'.
Level 1  Numbers up to 10
Level 2  Numbers 10 to 19
Level 3  Brackets included
Level 4  Decimals included
Level 5  Advanced (including fractions)

Answers to this exercise are available lower down this page when you are logged in to your Transum account. If you don’t yet have a Transum subscription one can be very quickly set up if you are a teacher, tutor or parent.
You can print out the levels of this exercise individually or download a pdf version of all five levels in structured worksheet format.
You need to know about the order of operations in order to complete this exercise. This is how I remember the order:
BIDMAS is an acronym reminding pupils of the order of operation used when evaluating expressions involving a number of different operations. The letters of BIDMAS stand for:
When only addition and subtraction (or only multiplication and division) are left in an expression you should work them out in the order you find them, starting from the left and working towards the right. The blue image of the letters above has been designed to show that multiplication and division have the same importance as the letter M is in the same position as the letter D. The same can be said for the letters A and S.
For example, to evaluate the expression 3^{2} + 5 x 7  (4  3)
Work out the brackets first which gives 3^{2} + 5 x 7  1
Then the indices 9 + 5 x 7  1
Then the multiplication 9 + 35  1
Then the addition and subtraction in the order they are given
The answer is 43
