Download PowerPoint Maths Games – Multiplication Flash Cards.
This Random PowerPoint Multiplication Flash Cards Generator is created specifically for elementary mathematics teachers and students (3rd to 5th grade).
There is only one slide that updates automatically with new questions. There is also a scoreboard to keep track of the number of questions answered correctly.
It tests the efficiency and accuracy of the student. There is a scoreboard that keeps score of number of multiplication arithmetic questions answered correctly.
RND function in Visual Basic Application generates a random number of the data type Single which is less than 1 but greater than or equal to 0.
Remember to use the Randomize Function before using the RND Function. The Randomize Function makes the order of the random numbers generated random.
We have to use the following formula in our PowerPoint Maths Games Visual Basic Application code to make sure that the generated random number is between a specific range:
Q1 = Int((upperbound - lowerbound + 1) * Rnd + lowerbound)
Here, upperbound is the highest number in the range, and lowerbound is the lowest number in the range. This allows us to select the range from which the Multiplication Flash Cards would be generated.
We store the generated number within Q1. Similarly, we store another number as Q2.
The two numbers are then shown in the Question Textbox using the .TextFrame.TextRange property of a shape.
Sub GenerateQ() Dim QShp As Shape 'setting shape' Set QShp = ActivePresentation.Slides(2).Shapes("Q") 'setting range' L1 = 3 L2 = 15 'generate two random numbers' Randomize Q1 = Int((L2 - L1 + 1) * Rnd + L1) 'formula' Q2 = Int((L2 - L1 + 1) * Rnd + L1) 'formula' 'insert random number in question' QShp.TextFrame.TextRange = "What is " & Q1 & " x " & Q2 End Sub
We use an ActiveX TextBox element which allows the student to type their answer in slide-show mode.
We use an if-then condition to check whether the attempted answer is the same as the correct answer, which is the product of our two integers Q1 & Q2.
Based on that, we increase the number present in our scoreboard: CAShp and WAShp which stands for Correct Answer Shape & WA Answer Shape respectively.
You can use a ActiveX Element Label instead of a Shape to make your work simpler. as the .Caption property would suffice to change the text within the Label.
With the shape, we would have to first define where it exists and then use the .TextFrame.TextRange
Sub Initialise() Set CAShp = ActivePresentation.Slides(2).Shapes("CA") Set WAShp = ActivePresentation.Slides(2).Shapes("WA") A.Value = "" CAShp.TextFrame.TextRange = Int(0) WAShp.TextFrame.TextRange = Int(0) End Sub
Sub CheckA() If A.Value = Q1 * Q2 Then CAShp.TextFrame.TextRange = Int(CAShp.TextFrame.TextRange) + 1 Else WAShp.TextFrame.TextRange = Int(WAShp.TextFrame.TextRange) + 1 End If A.Value = "" GenerateQ End Sub
After updating the scoreboard, we reset the value of A (Attempted Answer ActiveX TextBox Element) and generate a new Multiplication Question.
Let us assume our Q1 is equal to a random number that was already generated.
We can introduce a 50-50 probability to convert that into a negative number with the following syntax:
If Rnd > 0.5 then Q1 = Q1 * (-1)
If the answer results in a negative number, the student would have to type the answer following the hyphen symbol – denoting the negative expression,
We can use this multiplication module to create random flashcards for addition & subtraction too. You’d have to just change the range of the random numbers that are generated and you’re good to go!
