2. This presentation has mouse clicks disabled to prevent accidental clicking on to the next slide. In order to move on to the next part of the show, you have to press ENTER on the keyboard. The only point that mouse clicks (or touch screen if using an interactive white board) will work on is the answer buttons and the page turning buttons on the “try again” and “well done” screens.
Press ENTER to make the sum appear. Read it aloud, and ask questions relating to it, such as “How many things do we need to start with?” or “What do you think the answer will be? Will it be more or less than x?”
Press ENTER to cause the set of objects to appear. They will appear one by one with an audio cue - encourage students to count along with these.
Press ENTER to cause three of the objects to be crossed out. This will be accompanied with audio cues - encourage students to count along with these. Discuss that three things have been “taken away”. Discuss that this term is figurative - what we are really trying to find out is what X less than Y is.
Ask students to count how many objects are left, and find their answer on a number line, number fan or write it on a whiteboard or in their head. Then press ENTER to make the three “Answer buttons” appear. Ask the students if anyone can see their answer on these. Select someone to give their answer. They can use a mouse or touch screen to click on their choice.
If the answer is correct, the “well done” screen will appear, with a button to click to go on to the next slide.
If the answer is incorrect, the “try again” screen will appear, with a button to click to go back to the slide with the sum on it and have another go.
Repeat for the remaining slides. The slide show will finish automatically after the last slide has been completed successfully.
