As part of the series Primary Lesson Starters, this Teachers TV video consists of six mathematical problems for use in class with an interactive whiteboard. A suitable year group is suggested at the beginning of each starter. The scenarios focus on incorporating mathematics into real-life situations and include: • Agatha and her sisters is a puzzle aimed at students in Year Four or Five. Students are asked what fraction of a group of sisters and their dogs can travel in a mini at one time. • Pizza party allows Year Three and Four students to practice using fractions to share a pizza out equally. • Running on empty is a puzzle which involves calculating how often a high-speed train needs to stop and re-fuel and is aimed at students in Year Five or Six. • Muddy ears is a puzzle for students in Year Three or Four.
