Performance
• Students could use concrete materials, such as blocks or counters 
and the balance scales, to find the value of 
p
in the following 
equations. If necessary, model the use of guess and test as one 
strategy. By observing patterns in their results, students become 
more systematic in the guesses they make.
3 + 
p
=11 
14 - 
p
= 8 
 p 
- 9 = 16 
3
p 
= 12 
p
+ 5 = 17 
24 = 
p
+ 9
25 = 35 - 
p

Paper and Pencil
• Ask students to draw a diagram to represent and solve the following 
equations.
n
+ 12 = 19
k 
= 14 – 3 
9 +
 d
= 16 5
m
= 15
(5PR2.2)
• Tell students:
There are now 11 muffins on a tray. There were 24 at the start; some 
have been eaten. How many muffins are missing from the tray? 
Ask students to write an equation to represent the problem. Then 
solve it. Is there another possible equation for the same problem? 
Explain.
(5PR2.1, 5PR2.2, 5PR2.3)
• Ask students to solve the following equation and explain their 
thinking.
c
– 12 = 8
(5PR2.2)
Journal
• Ask students to respond to these prompts:
(i) Explain how you would solve the equation 21 +
 y
= 40 .
(5PR2.2, 5PR2.3)
(ii) Fran is 3 years older than Hannah. Hannah is 21 years old.
How old is Fran? Write an equation to solve the problem and
then solve the equation. Is it possible to write a different
equation for the same problem? Explain.
(5PR2.3)
