7HspreadsheetsThis week:Spreadsheets- functions and formulaeSTARTERCheck your emailsThis week I have made another workbook for you to complete.

Open the file attached to the email I have sent you.Complete the starter activity on the first tab.

Please let me know if you missed last lesson.Learning objectivesDifferentiate between label, value and formulaImplement formulae confidently in ExcelExplain the use of the SUM and AVERAGE functions

SOME:

Apply knowledge of formulae and functions to help model solutions to scenarios

Label, Value, FormulaMini-plenary:

Someone give me an example of:-

A labelA valueA formulaWhat is wrong with this formula?=1A+3GCELL REFERENCES USE COLUMN LETTER, ROW NUMBER=A1+G3REWARD POINTS!!!What is wrong with this formula?=AA10A10WE DONT USE , WE USE /!=AA10/A10What is wrong with this formula?W10-Z13ALL FORMULAE BEGIN WITH ==W10-Z13What is wrong with this formula?=A6xA7We use * for multiply, not x=A6*A7What is wrong with this formula?=A1+A2+A3+A4+A5Use functions such as SUM to make formulae shorter.=SUM(A1:A5)Rules for FormulaeFormulae always start with the equals symbol =We use * to multiply not X!We use / to divide, not Functions such as SUM and AVERAGE can help us write shorter formulae.FunctionsSUM is the function we use to total a list of numbers.A volunteer to show how we would work out the total of the numbers in column D!

FunctionsAVERAGE what is an average?How do we work this out in maths?What is the average of the numbers in row 7?A volunteer to show how we would work out the average of the numbers in row 7.

Main ActivityFinish the Starter Activity tab if you have not yet completed it.Move onto the SUM and AVERAGE tab.Ask the person next to you if you need help, else ask me.

If you finish, move onto the Modelling #2 tab. Only use the help buttons if you are really stuck!ModellingModelling is the process of designing a computerised solution to a real-world problem or scenario.

Another volunteer needed!Bessy has 3 cats and 1 dog and spends 5 a week on her pets.

Albert has 0 cats and 2 dogs and spends 10 a week on his pets.

Jill has 9 cats and 1 dog and spends 23 a week on her pets.PLENARYQuiz your classmatesRemember our learning objectives:
