HCF and LCM
The below QQI Worksheets © Activity generates different types of paper based resources using the QQI random question system. There are 5 different activities to choose from, all of which are designed to be easily printable:
First choose if you want question on the Highest Common Factor or Lowest Common Multiple (or choose Random to get a mixture of both).
Next choose if you want 2 or 3 numbers to appear, again choosing Random will give a mixture.
Now choose the size of the numbers you want to deal with.
Once you have chosen the attributes, press Generate Activity and you will be taken to another page with the activity ready to print.
 The standard Worksheet, with as many as 100 questions. Choose how much working space you want to provide (Very Small fits 40 questions per page, Small fits 30, Medium fits 18, Large fits 14 and Very Large fits 6), and give the worksheet a title. I like to use these as a "How Many Can You Do" style activity, where I give students 10 minutes to do as many as they can. They could also be used for relay races (like the QQI Relay but paper based). The answers for all the questions are printed on a separate page at the end.
 The Treasure Hunt option produces a set of treasure hunt cards for placing round the room or to be used as a set of loop cards in small groups. You can choose how many cards there should be (from 4 up to 40 in multiples of 4), and how many cards there should be per page (either 4 medium sized cards or 1 large card). The answers to each individual card are supplied as is the correct loop based on the card numbers.
 The Odd One Out activity is based on an excellent resource found on TES uploaded by UKDana. There are 16 answers in a grid, and 15 questions given. Each question matched with one of the given answers, leaving one spare answer at the end, the odd one out. An extension is also provided to find as many questions to give the final answer as possible. Again, full answers are provided.
 The Codebreaker activities are always popular with students. There are 26 questions, each with a different answer that links to a letter of the alphabet. Students then use these answers to decipher a message at the bottom of the page, which could be a maths joke, a general joke, or a wise/motivational quote. The answers to each letter are provided, as well as the full message. If you have any good jokes/quotes that would work well (they need to be fairly short), then please Contact Me.
 The Matching Cards activity could be used in a variety of ways in the classroom. It produces either a 4x4 or 5x5 grid of questions on one page and answers on the next. Students could be given these to cut out and simply match, or to add a bit of competition, turn it into a memory game (print questions and answers on different colour paper, and have them laid out in a square, upside down, and one student turns one over from each group, and if they match they win the pair). Other options are: Connect 4 style games where students compete to get a line of 4 correct answers, taking turns to pick a square to answer; Thoughts and Crosses is a similar idea based on the game TicTacToe; or a manual Bingo game, where students are shown the answers to choose from, you cut up the question cards and take one at a time randomly.
First choose if you want question on the Highest Common Factor or Lowest Common Multiple (or choose Random to get a mixture of both).
Next choose if you want 2 or 3 numbers to appear, again choosing Random will give a mixture.
Now choose the size of the numbers you want to deal with.
Once you have chosen the attributes, press Generate Activity and you will be taken to another page with the activity ready to print.
