Maths and logical thinking have proven to be extremely beneficial to a child’s development. Kids learn how to recognise patterns, sequences, seriation, spatial relationships, object permanence, etc. These skills can be cultivated early by letting children play with educational toys and cubes and by helping them learn with maths workbooks, which can be found on sites like Hope Education. Maths seems to be one of those subjects at school that you either love or hate. But many think that primary school maths questions should be solvable by everybody. We’ve put together a list of 10 maths problems that primary school pupils from Singapore are faced with on a daily basis. See if you’ve got what it takes to crack these logic puzzles. Ella enters the forest of forgetfulness and meets a lion and a unicorn. The lion lies on Mondays, Tuesdays, and Wednesdays, the other days he speaks the truth. The unicorn lies on Thursdays, Fridays, and Saturdays and speaks the truth on all other days. The lion says: “Yesterday I was lying.” to which the unicorns responds: “So was I.” On what day did they say that? The king sentenced you to death, but he gives you a chance to be set free. He hands you 50 white marbles, 50 black marbles, and two empty bowls. He asks you to divide the 100 marbles in any way you like among the two bowls. You’ll then be blindfolded while the king will mix the bowls around. Then you’ll have to choose one bowl and pick one marble. If the marble is white, you’re free, if it’s black, you die. How would you divide the marbles to have the best chance of being set free? A little girl is 2 years old, but her sister is only half as old as her. When the first girl is 100, how old will her sister be? A woman has to get a fox, a goose, and a sack of corn across a river. Since she only has a small rowing boat, she can only take herself and one other thing with her. If she leaves the goose and the fox alone together, the fox will eat the goose. If she leaves the goose and the corn alone together, the goose will eat the corn. How can she transport everything and make sure that all of them arrive safely on the other side?

If Sally gives Dave a pear, they’ll both have the same amount. However, is Dave gives Sally a pear, then Sally will have twice as many as Dave. How many pears do they each have? Your sock drawer is full of unpaired black and white socks. If you close your eyes, how many times will you have to reach in to guarantee having a matching pair?
