2. Students used an egg cutter to divide eggs in equal slices and calculated the
volume of each cylinder. Then they calculated the total volume by adding the
the volume of all slices. For the end parts they subtracted a little bit because
these pieces were no full cylinders. They compared the volume that they had
calculated by this method with the calculation via formula V =2/3*PI*a^2*b.

Some students prepared a hands-on activity for their class and leaded small
groups of 4 or 5 that worked around (a-b)².

4. Young students like to discover maths while playing. There is a lesson plan
how to use the playmobil dolls to introduce calculating with negative
numbers.

5. A lot of round plates, boxes, … are measured and the ratio of perimenter and
radius is calculated. So students detected by themselves that there is a
constant, called PI.
Pictures, lesson plan and evaluation ...
Discovering PI by measurements
6. A lot of activities can be done by using plastic forms. The basic forms are
triangles (isoceles, right-angled), squares, pentagons and hexagons. The
material is called Polydron and can be ordered easily via internet.
You may order Polydron here (the coffret is enough for groupwork in a class)
Platonic and other solids with Polydron
7. It is another way to build solids. It is more creative than using Polydron. You
also can take thin straws. It is important that the Plasticine is hard enough!
A lesson plan will follow!
Solids with tooth peaks
8. Students normally know Archimedes principle from their physics lessons to
determine the volume of a solid. Students may compare the results with the
the formula V=2/3*PI*a^2*b to calculate the volume of an egg.
Determing the volume of an egg
9. Students like this game to determine suitable probabilities for different
positions and then calculating probabilities for positions if two or three pigs
were diced.

11. Draw some graphs of degree three or four on the schoolyard. Students have to
walk along the graph pointing with the right arm on the ground if there is a
right curvature, to the left if the graph curves right.
So students really get to know the meaning of an inflection point of a graph.
Graphs on the schoolyard
12. Students discovered reflections and the relation between the angle between
two mirrors and the number of mirror images.
Look at the task (in German) and the evaluation report
Experiments with two Mirrors
13. Students discovered the concept of solving equations by doing equivalent
transformations hands-on.
Students’ report and lesson plan will follow!
Experiments with matchboxes and matches
14. LÜK system (abreviation of learning- training-control) consist of of a box with tiles with
numbers on one side and a colored pattern on the other side. It is used in cobination with a
booklet e.g. for booklets for fractions, percentages or word problems. 24 tasks have to be
solved. By placing the tiles on the correct square a multicoloured, symmetrical control
pattern is formed on the back of the tiles.

15. KUBUS is a game for younger students to practise and improve their conception of
space.
The left picture shows a game with nice looking tiles that can be ordered here. On
the right picture you can see that this game can be easily made with colured
corkboard.
There is an english description of the rules, too.

16. So-called elastic thera-bands for gym can be marked with a water-soluble pen
with 100% referred to the length of classroom’s tables. Then the elastic band
is divided in 10 distances, so that you get a scale from 0 % to 100 %. Then
different objets in the classroom can be maesured and the lengths can be
indicated as percentages of the table’s length.
Percentages with an elastic band
17. More hands-on activities that we used in
different classes will follow in pictures and
videos, with lesson plans and worksheets,
too.
