Start with white light
Every verb begins in the first column: go, eat, see. That plain form is our white light.
Every verb is white light. Steer the beam through the prism and it splits into its past: warm light for the past simple, cool light for the third column.
The idea
White light holds every colour. A verb holds every form. Dig's Prism turns one of the hardest parts of English grammar into something you can see, move and remember.
01
Every verb begins in the first column: go, eat, see. That plain form is our white light.
02
Move the light into the glass. Like real light, it bends and splits into a rainbow of colours.
03
Warm light shows the past simple. Cool light shows the third column. New colour, new form.
Real physics, real refraction. In a prism, red light bends the least and violet bends the most. So the warm end of the rainbow points to the past simple, and the cool end points to the third column.
Two separate parts
Learn them one at a time. Part 1 is all about the past simple. Part 2 is all about the past participle. Each part has its own lab, its own lessons and its own games.
Quizzes and games
Every round is new, every sentence is short and every right answer explodes into colour. Students play, teachers watch the verbs stick.
For teachers
Designed for English teachers and their A1 and A2 learners. Open it on the projector, hand the light to a student, and watch the whole class lean in.
