Lesson 3 term, expression, equation and substituting

Entry ActivityConvert between fractions decimals and percentages

Fraction Decimal Percentage

½

0.1

¼

20%

0.6

Divide the numerator by the denominator to get a decimal

Multiply the Decimal by 100 to get the percentage

Divide the percentage by 100 to make it a decimal

0.1 becomes 1/10 because it’s is 1 in the tenths column. 0.01 is 1/100

Heard it but not sure what it means

Never heard it before

What it means is...

Variable A letter used in algebra to show the value can change e.g. n (n can be any number)

Term Algebra containing only letters (but could have a number attached) e.g. n or 3n

Expression A combination of letter numbers and mathematical signs e.g. 3n – 2, 5 + a, 6p - q

Generate Make it e.g. Generate a sequence means make one!

Sequence A list of numbers, pictures or letters that have a pattern.

Describe You explaining something in detail

We are going to generate some algebraic terms and expressions...sounds hard, but it’s not!

a) Add 3 to ab) Multiply b by 9c) Take 14 from cd) Divide 20 by de) e divided by 2f) f minus 1g) Increase g by 4h) What are the red questions? Term or expression. Why?i) What are the black questions? Term or expression.

Why?

We are going to generate some algebraic terms and expressions...sounds hard, but it’s not!

a) Add 3 to a a + 3b) Multiply b by 9 9bc) Take 14 from c c - 14d) Divide 20 by d 20/d (or 20 ÷ d) e) e divided by 2 e/2 (or e ÷ 2) f) f minus 1 f - 1g) Increase g by 4 g + 4h) What are the red questions? Term Why? Because it’s all

attached togetheri) What are the black questions? Expression Why? Because

there is a sign in there

Show me how confident you are to do the next task on this!
