Ch 8 Algebra

Goal(s)

                                                            

                            > I recall my knowledge about squares,                                                        and I work together

                            > I can recognise and collect like terms

                         

                            

Lesson content

> Squares = a number times itself

> Concentric circles => - Choose 3 different squares + solutions

                                                 - Write them on a post-it   

                                                 - concentric circles

> Collect like terms

                                                

5​2​​=25

Squares

Square => a number times itself (or even: a variable times itself!)

5​2​​=5⋅5=25

b​2​​=b⋅b

       Choose 3 squares (+answers)

choose 3 squares

 between 3 and 15

and write them on your note:

a.

b.  ....

c.  

(e.g. 3 squared equals 9)

4​2​​=16

CLIL Concentric circles 

> form 2 circles (don't forget your note.....)

> Inner circle starts => name e.g. "3 squared equals ......."

                                                person in outer circle answers.....

circles

Like terms (and unlike terms)

a, 2a, 5a => like terms

                 unlike terms  (because                           )

a,a​2​​

a​2​​=a⋅a

Homework

Make of 8.1: exercises 13, 14 and 16abcd and check your answers
