📈 Patterns and Algebra

This quiz explores the foundations of patterns and algebra in Grade 5 mathematics. You'll learn to identify and extend numeric and geometric patterns, create patterns from rules, represent patterns in tables and graphs, and write algebraic expressions using variables. Understanding these concepts builds your problem-solving skills and prepares you for higher-level algebra. **What you'll learn:** - How to identify and extend patterns in sequences - How to represent patterns using tables and graphs - How to write algebraic expressions with variables - How to understand variables as unknown quantities and placeholders - How to create patterns from given rules

Question 3
The pattern 5, 10, 15, 20, 25 can be described by the rule 'multiply the position by 5.'
Question 4
A table shows the relationship between hours worked ( $h$ ) and money earned ( $m$ ). If you earn $8 per hour, which algebraic expression represents your total earnings?
Question 5
Which sequence follows the rule 'start at 10 and subtract 2 each time'?
Question 6
In a geometric pattern, a row has 3 squares. The next row has 6 squares, and the row after that has 9 squares. How many squares will be in the fifth row?
Question 7
Which table correctly shows the pattern $y = 3x + 1$ ?
Question 8
A variable in algebra can represent any number and changes depending on the situation.
Question 9
If $x = 5$ , what is the value of $2x + 3$ ?
Question 10
A pattern of dots is arranged so that Position 1 has 2 dots, Position 2 has 4 dots, Position 3 has 6 dots. Which expression shows the number of dots at any position $n$ ?
Question 11
On a graph, points form a line showing a pattern. If the points go from (1, 2), (2, 4), (3, 6), and (4, 8), what is the pattern rule?
Question 12
The sequence 1, 4, 9, 16, 25 represents the pattern of perfect squares.
Question 13
