Mad Math is a problem solving based set of math activities for primary students. The basic aim of the series is to cloak the cognitive processes involved in problem solving in an attractive, enjoyable exterior.The activities are often fun ... mad even, but the basic underlying principles are sound. Ordering these activities according to difficulty is extremely hard to do because student readiness for problem solving relies greatly upon their previous experiences and how the material is presented in the classroom. Similarly, it is hard to classify these books according to year level. Basically, Book 1 is framed for Primary (Grades 1 - 3), Book 2 for Intermediate (Grades 3 - 5), and Book 3 for Middle School students working at Grade 6 - 7 levels. These levels are not prescriptive, thus materials should be selected to suit the student, group or class. The aim of Mad Math is to develop problem solving skills rather than other, more mechanical number skills. Any aid which assists in getting the problem solved is to be encouraged as the process is much more worthwhile than the answer in this case. Calculators, blocks, counters, squared paper, pieces of paper to draw on, and indeed anything that helps the process of problem solving should be encouraged and made available.

To get the best out of Mad Math

Each Mad Math page has three parts to it:

1. The Problem Read through the problem with the student, group, or class you are using it with. Whilst reading for meaning is a very important skill major emphasis here is problem solving skills
not reading. So, ensure that all students understand and are fully aware of the problem presented. Discuss the problem before progressing to the questions, perhaps developing your own questions
before moving on.

2. The Questions Ensure that all the students understand the question and its context before they tackle the
answer. The benefits flow from the process not the answer. In fact many students will have
difficulty in framing a form of attacking the problem. Discussing the questions helps overcome this.

Independence will develop with experience.

3. Madness ... The Extension The final task adds a further fun dimension to those on the page. These activities may not be
totally math orientated but they lend an enjoyable end to a math session. The ‘Madness’ boxes are intended to be optional.

Assessment In assessing these activities it is essential to consider more than just the answers. "Did the student understand the problem?" is probably the most important question to be asked and evaluated. Questions about computational accuracy are of secondary importance ... but important nevertheless. Do not forget to evaluate your own presentation of the material ... using materials such as this as ‘busy work’ may indeed cause more work than was intended.

Worksheet 9

Serge the human fly was crawling up the side of the world’s tallest fence outside the world’s largest garbage dump.

The fence is 200 meters high. Serge climbed 40 meters every 30 minutes but was blown back by the wind 30 meters in the next 30 minutes whilst he was getting his breath back.

Finally after a struggle and quite some time he got to the top of the fence and launched himself at the great mound of garbage before him, only to be knocked flat by Frank the human flyswat.


1. How tall is the fence Serge is climbing?

2. How far does Serge climb in the first 30 minutes of each hour?

How far is he blown back by the wind?

3. How much gain does Serge make each hour?

4. How long does it take Serge to reach the top?

5. Draw a diagram of Serge’s journey on squared paper to check your answer.

Was your answer correct?
