As a maths starter today, we are going to play Countdown: https://nrich.maths.org/6499
You can either choose 6 of the cards (the 4 at the top are either 25, 50, 75 or 100, and the cards on the bottom row are less than 10), or choose quickstart (it will choose the cards for you to play with). Press play and it will choose a total number. Try to make that total number using any of the 6 cards, but you can only use each card once (it doesn’t matter if you don’t use all the cards). You can add, subtract, times or divide. In the TV programme, the contestants are only give 30 seconds, but I won’t be that mean! Try and get an answer within 5 minutes, or set a timer and see how long it takes you. Keep trying different calculations. Don’t worry if you’re finding it tricky after you’ve given it a go for 5 minutes; there’s a solution shown. Remember to be resilient; see if you can get the answer, and/or improve your time!
Today, you will be applying your place value skills to solve the riddles. Think carefully about each clue and what column each digit is in. There are 3 sets of challenges, so choose 1, 2, or 3 stars depending on how confident you feel. Remember, if try one question and it’s easy, try the next challenge up.
Extension: make up your own riddles!
(NB. Don’t worry if you don’t have a printer… you can either work off the screen or copy the questions to paper).
