Topic: Fraction Problems
Strategy: Drawing diagrams
In some fraction problems the whole is not given. A common mistake you might make is to multiply the fraction by any of the numbers in your problem. Don't be too quick to multiply. I suggest drawing a diagram of the fraction you are unsure of, then use it later. Take a look at these questions to see how drawing helps. |

Topic: Problems involving Average
Strategy: It's important to remember that averages can change by either increasing it or decreasing it. Here is a look at an example question.

NB: There is a slight error in the problem (294 should be 304. )
Ron did 2 more tests, so his mean changed from 76 to 80. Let's take a look.

Topic: Unequal Sharing
Strategy: Draw a diagram to explain the comparison statements. In this question there is a change that results in an unequally shared number of oranges between the two children. Let's take a look. |
Hi Lisa, I hope this helps improve your understanding of bar models 
Changing ONE word in this question could make a BIG difference in the diagrams we draw. Let's take a look.
Hi Annis, I hope this video clears up any confusion your child is having. Strategy: In the past I would have mentioned "If a clue is not yet useful, rest it and move on." This is still an excellent suggestion but be aware of comparison statements like the one found in this problem.

Topic: Time
Strategy: Many time questions can be solved using a timeline.
In this question we can use the timeline to add or subtract time mentally. Remember students you must learn the skill of converting minutes to hours and hours to minutes. |
Hi Anjanique, I totally understand why this question could be a bit confusing. Here are tips for solving it.

Topic: Bar Graphs
Top Tip: If a clue is not yet useful, rest it and move on. Be sure to come back to it when you can. In this question students are given clues in order to complete a graph. Here are some things to pay attention to:

Hi Talya and Zariah! Let's see the distributive law of multiplication in ACTION! Topic: Distributing Multiplication
Strategy: We can share one of the factors in a multiplication problem into an addition bond This creates smaller multiplication problems that add to give the original product. 20 x 13 = (20 x 10) + (20 x 3) |
In this third video I explain how to calculate unknown amounts using the distributive law of multiplication.
Understanding distributive law using area/arrays
In this video I recap the use of the distributive law as an algorithm.

Topic: Fractions (Line Models)
Strategy: Represent fractions on a number line. Learners me be allowed to encounter different ways of representing fractions: linear, area and set models. Too often, teachers focus on area models using rectangles or circles to describe fractions. |
