A one-page exit ticket on combinations of two variables for Year 6 maths. Pupils list every pair of positive whole numbers where a + b = 6, then count the sandwich-and-drink combinations a cafe can offer from 3 sandwiches and 2 drinks. Three identical slips sit on one page, so a single print serves three pupils. Matched to two England National Curriculum algebra objectives.
Algebra
“Find pairs of numbers that satisfy an equation with two unknowns”
The first question asks for every valid pair, not just one.
Algebra
“Enumerate possibilities of combinations of two variables”
The cafe question counts combinations systematically.
Pupils list all the pairs of positive whole numbers that work.
Three sandwiches and two drinks; pupils count the possible meal combinations.
Each slip closes with a five-emoji feelings check.
Exit ticket
Two questions fit the final five minutes of an algebra lesson.
Assessment check
Complete lists show systematic thinking; missing pairs show where to reteach.
Lesson starter
Also works as a recall warm-up the day after teaching combinations.
