Parent: Ben really enjoyed this activity. He estimated quite closely on most of the items. When estimating the number of videos he had the idea that if 2 videos fitted on the book and 13 books fitted on the paper then 26 videos would fit on the paper, Unfortunately, because of small fractions his answer was inaccurate, which was a bit disappointing for him.

Teacher: But I expect it was close. Estimates are best guesses.
