World's Top 10 Most Interesting Elementary/Primary School Maths Problems

Today, our MathSloth team took some time off to compile a list of what we feel are the world's Top 10 Most Interesting Elementary or Primary School Maths Problems (to date).

Some of these maths problems, on their own, have generated much Internet debates, but more importantly, they represent interesting boundaries that we may use to challenge our students' thinking in the formative elementary school stages. We will explain which area of mathematics each of these questions attempt to test.

Note that the maths problems are not ranked, they are merely listed in reverse grade order. (no answers disclosed in this post)

What it tests. This problem tests pattern association between '882' and (clue) its pictorial representation and deductive reasoning on the arithmetic structure of the pictorial presentation to yield the 2 numbers that can be…

Reading a Progress Report

Progress Reports. As your child completes more practices and unlocks more difficulty levels in MathSloth, it is useful to review how far he has come in his mathematical learning journey. The Progress Page provides these insights.

Timeline of Practices. For each practice series that your child has attempted, a progress report is automatically generated and incrementally accumulates his past practices. For each practice series, MathSloth breaks down progress by the difficulty level.

For each difficulty level, MathSloth provides the latest analysis at that level, as well as your child's recent practices and score. This is followed by a tabular list of the timeline of practices that your child has completed over time. You may then view the practice report of each practice by clicking on the view link on the right side of each practice.

Here's a sample!  You may also be interested to view one of our user's sample practice report.Sally's Practice Report

Reading a Practice Report

Practice Report. MathSloth automatically scores your child's practice and generates a practice report for each practice. 

Analysis. A practice report contains an analysis of the child's performance for the practice. The analysis may be positive if your child has done well at the practice and may also point out areas of weaknesses and strengths in your child's practice.

Practice Results Section. The practice results section lists out the 10 test questions in the practice and whether the questions were answered correctly. If a question was answered incorrectly, the correct answer is then provided.

Practice Score/Achievement Section. The practice score/achievement section shows your child's total score for the practice and whether the practice has earned a new star or unlocked new difficulty levels.

Next Actions. You can continue with another practice, switch to another practice series, review your child's progress or share this practice report. All practice data are kept…

Starting a Practice

Select a Practice. Choose any of the practice series shown in the MathSloth Practices page.. For children in preschool or kindergarten, we would recommend starting with the Count, Sequence, Pattern and Compare practice series. For children in early primary/elementary levels, you may wish to start with the arithmetic Add, Subtract, Multiply and Divide practice series.

Select a Practice Level. Generally, your child can continue the practice at the most recent practice level. However, he or she can also perform practices for earlier practice levels that were completed.

Practice Lobby. The practice lobby confirms your selection of the practice type and level. There are 10 questions for each practice and answers will only be revealed at the end of the practice. Answer 8 out of 10 questions correctly to earn a star!

Let's Start. For each question, your child may either skip the question or submit an answer.

Practice Report. Once the 10 questions have been responded to, MathSloth instantly s…

What have I practiced so far ?

MathSloth provides a quick overview of the practices your child has done both at the Practices and the Progress pages. The overview depicts which practice series your child has started on and which your child has not started on.

For the current practices, if your child has started on a practice series, you may initially see number of practices he or she has done, or the number of Stars earned from the practices.

As your child completes one or more difficulty level, he or she will start earning Level Badges as shown here:
When your child finally completes the practice series, he earns the Series Badge and a Certification of Completion for the practice series and hurray ! It is an amazing milestone for your child !

Basic Arithmetic + - x ÷

Between kindergarten to early elementary/primary school, the child learns about basic arithmetic. MathSloth's arithmetic practices + - x ÷ are designed to assess your child's grasp of basic arithmetic before they learn to apply basic arithmetic to solve problems. These are basic, but nonetheless important, assessments that affirms your child's ability to handle arithmetic operations for numbers from 0 to 50.

Difficulty Levels. For each arithmetic practice series, we have designed 6 levels of difficulty. For addition and subtraction, we first assess the child for adding operations involving numbers 0 to 10, progressively increasing the number ceiling to 15, 20, 30, 40 and finally to 50. For multiplication and division, our progression starts with 5 (instead of 10), followed by 10, 15, 20, 25 and a wider jump to 50. From empirical tests in classroom environment, we observed that having tighter assessment ceilings in the initial difficulty levels (10, 15, 20 for addition/subt…
