Fill in the missing words:

It was Monday morning and Sam sat down at his normal desk in the classroom. The teacher, Miss Tayke, wrote out the following Correct Wrong on the white board.

8x - 4 = 12

Sam could see that the Correct Wrong on the left side of the equals sign had two Correct Wrong which had a common Correct Wrong . He could think of two ways of solving this Correct Wrong . He could add 4 to both sides or he could factorise the left side.

All of a sudden the teacher exclaimed "Gosh! I've made a mistake. What I should have witten on the board was..."

8x - 4 > 12

Sam wondered how he should solve this Correct Wrong . He remembered that multiplying both sides by a negative number would have the effect of reversing the Correct Wrong sign but that is all he could remember.

Miss Tayke reassured that class by saying that this Correct Wrong can be solved in the same way you would solve a simple Correct Wrong .
"Adding four to both sides gives...".

8x > 16

"Now divide both sides by the common Correct Wrong of 8 to produce this solution."

x > 2

Sam could now see that any value of x bigger than 2 would satisfy the inequality that Miss Tayke had written on the board.

Why am I learning this?

Mathematicians are not the people who find Maths easy; they are the people who enjoy how mystifying, puzzling and hard it is. Are you a mathematician?

"Love using the Starter of the Day activities to get the students into Maths mode at the beginning of a lesson. Lots of interesting discussions and questions have arisen out of the activities.
Thanks for such a great resource!"

Go Maths

Learning and understanding Mathematics, at every level, requires learner engagement. Mathematics is not a spectator sport. Sometimes traditional teaching fails to actively involve students. One way to address the problem is through the use of interactive activities and this web site provides many of those. The Go Maths page is an alphabetical list of free activities designed for students in Secondary/High school.
