Grade 7 · 3 pages · A4What each level generates
Grade 7 from a trial — the exact skill behind each difficulty setting, straight from the generator.
- Level 1Spins recorded
- Level 2Draws recorded
- Level 3Two outcomes together
Grade levels follow the progression common to most English-language curricula — not one specific national curriculum. Every level shows exactly what it generates, so you can check the fit with your own program. See the full scope & sequence →

Frequently asked questions
▸Which Common Core standards do these sheets cover?
7.SP.C.6 and 7.SP.C.8b. The first is approximating the probability of a chance event from its long-run relative frequency, which is the From a Trial sub-skill. The second is representing the sample space of a compound event, which is Counting the Outcomes.
▸How do you count the outcomes of two objects together?
Multiply the number of outcomes of each. A coin has two and a dice has six, so together they give twelve. The level-3 questions use three objects, where the same rule applies twice.
▸What is experimental probability?
The probability estimated from results that were actually recorded — spins, rolls or draws — rather than worked out from how the object is built. A spinner that stopped on red 14 times in 40 spins gives an experimental probability of 7/20.
▸How is this different from the Data Handling relative frequency sheets?
The arithmetic is the same and the situation is not. These questions record a chance process that could have come out differently; the Data Handling ones describe a group of people who have already been counted. That distinction is exactly the one Common Core makes between 7.SP.C and 8.SP.
▸Can I change how many questions are printed?
Yes, with the question-count stepper, and Shuffle gives a completely fresh set at the same level.
