Captain Halfinch

The Miscalculation of Cap’n Halfinch


Cap’n Half-Inch fears he has lost his ill-gotten gains for good until, that is, he happens upon a map that could lead him to the hidden treasure. But he soon finds out he’s not the only one after the booty… Who can solve the mathematical clues and get there first?

The Miscalculation of Cap’n Half-Inch is a swashbuckling tale of hidden treasure and mathematical conundrums based on the new maths curriculum and can be booked at three levels:

Key Stage 1: We look at number and place value, calculations using the functions and we introduce fractions.

Lower Key Stage 2: We build on this, looking at written calculation methods, adding and subtracting fractions and solving fraction and decimal problems.

Upper Key Stage 2: again we build on the above and we introduce long multiplication and division, multiply and divide fractions and decimals, and convert one to the other.
