Recognising, describing, and continuing number sequences including adding/subtracting a constant, doubling, halving, and multiplication patterns.
Where your child meets this in real life: Predicting future values, understanding growth patterns, or solving puzzles
SEAGReady breaks number sequences into 3 steps, taught in order so each skill builds on the last.
Continue sequences that count in multiples of 2-10 (e.g., 3, 6, 9, 12...)
Recognise and continue sequences with any constant difference, including subtraction (e.g., 8, 13, 18 or 50, 43, 36)
Recognise and continue sequences based on multiplication or division (e.g., 2, 4, 8, 16 or 80, 40, 20)
Three free sample questions from our number sequences course. Every question comes with a full explanation, and hints that guide without giving the answer away.
Noah is counting in fives. His count goes: 5, 10, 15, 20, ___. What number comes next?
What is the rule for this sequence? 9, 15, 21, 27, 33
Naomi folds paper and counts the layers: 2, 4, 8, 16, ___. How many layers after the next fold?
This is the exact interactive worked example your child sees in SEAGReady. Step through it and watch the method build up.
George is counting coins into piles of 5. His count goes: 5, 10, 15, 20, ___
What number comes next in the sequence?
5, 10, 15, 20, ___
Look at the gaps between numbers
Step 1 of 3
George is counting coins into piles of 5. His count goes: 5, 10, 15, 20, ___
What number comes next in the sequence?
The next number in the sequence is 25.
The key insight: Counting in multiples is just adding the same number each time - like your times tables!
Common mix-up: Adding different amounts each time. In a multiples pattern, the gap between terms stays the same.
These are the misconceptions we see most often in number sequences, including the ones our practice questions are specifically designed to catch.
Struggling with number sequences? The real gap is often in one of these earlier topics.
SEAGReady finds the exact step where your child gets stuck, teaches it with worked examples like the one above, and brings it back for review so it sticks.
