P4P5 Reverse Model Drawing (Before and After Fractional Change)

This exercise below aims to help students better understand before and after models by having them look at the already completed models and have them fill in the blanks to the original problem sum description.

While these are not exam questions, they help students to structure their thinking process for the formation of the equations(number sentences) needed to solve such questions.

Given the before and after model above, 
fill in the blanks.

Luke has ___ times as many toy cars as Marvin at first.

After Luke gave away __/__ of his toy cars.

He now has equal number of toy cars as Marvin.

Luke have 13 toy cars at the end.

They have ___ toy cars altogether at first. 

If the above question is easy, try to do the more challenging question below.

P5 Math: Overlapping Vertexes/Angles on a Straight Line

Angles are often thought of as easy questions that require little practice.

That is a common misconception of many P5 and P6 students.
Without practice, one will not be able to remember the rules easily.

Questions like these will often appear in Paper 1.
Calculator usage will not be allowed.

The question below will randomize with different numbers every hour.

P3/P4 Math: Before and After Model (Reverse Model Drawing)

With problem sums getting more complex as student progresses from P3 to P4, it will be difficult for the students to read the question and be able to draw the models required.

Hence, the "Reverse Model Drawing" method.

This method allows them to see the models first, and use it to decipher the question being asked instead.

With this approach, the student get to see the models already drawn and use it to fill up the gaps in the question being asked.

Once students have sufficient practice, they will be able to read the question and draw the comparison models independently.

P3/P4 Math: Reverse Model Drawing

To assist P3 and P4 Math students with comparison model drawing,
such visual aids may be useful.

Instead of having them draw the model, 
have them fill in a partially drawn model first.

If the student is able to fill in all the missing boxes, the model should be able to instruct them on how to find the answer.

The options order above will randomize every hour.

P3 Math: Part/Whole Models Practice ( Fill in the Blanks )

The following is a part/whole model drawing practice designed for students to improve their model drawing skills and "number sense" without having to read a problem sum.

Students are required to draw the model shown below and make use of 3 numbers given to fill in the blanks in the model and also use arithmetic calculation to fill in the 4th blank.

P3 Math: Comparison Model Drawing Exercise (More Than/Less Than)

The following is designed to help students visualise more than/less than questions by using comparison models.

These few questions may look identical 

but these numbers given are representing different parts of the model.

Draw the comparison models and fill up all the empty boxes in each model

Q1) 
Ali has $78. Ben has $30 more than Ali. How much do they have altogether?

Q2)
Ali has $78 more than Ben. Ben has $30. How much does Ali have?

Q3)
Ali has $30 less than Ben. Ben has $78. How much do they have altogether?

Q4) 
Ali and Ben have $78 altogether. Ali has $30 more than Ben. How much does Ben have?
