I am teaching year 7s apostrophes over a series of lessons. I initially ran a diagnostics 10 questions test, to see what the students already knew.
The site displays the results in easy table layouts. Whether they could the answer right or wrong, and if you scroll over the box it says how they answered the question.
I spent a lesson teaching the students the two ways of using Apostrophes and they engaged in activities to practice using Apostrophes.
Tomorrow the students will go back on NoRedInk and complete a post-test on Apostrophes. Again the site will display the classes responses to the questions, so I can easily analyses what the students have learnt and what they need to learn.
