The Teaching Page when projected onto a screen or interactive whiteboard allows you to go through the standard algorithm for multiplication showing each step of the process to your class. Every time you press one of the randomising buttons it changes the 3 digit multiplicand. Each button represents a different multiplier from 2 to 9, so you have an endless set of examples to practice with. The two printable Dynamic PDF Worksheets provide an (almost) infinite number of practice questions . 12 questions are laid out on the page. When any of the buttons (at the bottom of the page) is clicked all the 3 digit multiplicand will change. On Worksheet 1 each button represents a different multiplier from 2 to 9 , so for example you can have a whole page of 3 digit numbers multiplied by 4, or 5 etc. On Worksheet 2 each button represents a range of multipliers e.g. 3 to 6. Each row of questions will multiply the 3 digit number by a different number, first row by 3, second row by 4 etc. Answers are generated automatically every time. UK National Curriculum.

This resource has been expanded so there are now 2 Interactive Teaching Pages and 2 worksheets. “Adding up to 5 with Jellyfish 1” introduces the concept of adding and the symbols + and = by first counting two sets of objects and then selecting the equivalent total. The equation with numbers can then be revealed, one element at a time, and comparison between the two can be made. “Adding up to 5 with Jellyfish 2” invites the pupils to complete the addition sum and if needed do a check through counting. The 2 static worksheets cover most of the combinations of numbers that add up to 5 or less. See the “HELP” Page for further guidance. *Note This resource works with the official Adobe Acrobat Reader on Windows or Mac computers.

An introduction into sharing with ratio using the bar model as an ideal visual aid. Watch the video here for a quick tutorial on how to use these resources There is a teaching resource designed to be used on an Interactive Whiteboard or on a PC or Mac for one-to-one tuition. This is accompanied by a set of differentiated worksheets. Pupils are asked to share a quantity in a given ratio. A bar of the correct number of parts is created and pupils can either color in the bar in the ratio given and / or calculate the amount to go in each part. Another set of questions is based on being given the ratio & one of the final answers with the aim to find the initial quantity.

Percentage Bar Graphs provide visual support to help introduce percentages in an informal way by building on the equivalence of 50%, 25% & 75% and their fractions 1/2, 1/4 & 3/4 plus the knowledge that 10% =1/10 and 1/10th of any multiple of 10 or 100 can easily be found by removing the last zero of the number. From this starting point pupils can then proceed to calculate multiples of 5% or 1% of quantities. The Worksheets and Teaching Pages are set at 5 levels 10%, 25%, 50%, & 75% of multiples of 100 10%,20%,30% …90%, of multiples of 10 10%,20%,30% …90% of multiples of 100 5%,10%,15% … 95% of multiples of 10 Any percentage of multiples of 100 Answers will always be whole numbers.
