I decided to set the chidlers a fun home-school maths challenge involving Jelly beans. In this home we LURVE Jelly beans with a passion... so getting their attention was easy (especially when I said the Jelly beans could be eaten afterwards... I know how to motivate my kids!) I split them into two teams. The twins in a team & Roman & Smurf in another team. Roman & Chef always like to work together if at all possible so I chose the teams as a bit of a change & also Smurf got to learn some new computer skills as well as hard maths!
The challenge was to find out how much math-ish stuff they could do with a 100 gram bag of Jelly beans and to present their work attractively for a wall display. A pretty open-ended challenge. Chef & Tiger-girl worked together collecting data & presenting it on a poster...
They put 'flaps' on their poster to hide some of the answers.
Maths stuff covered by both teams included...
Probability, ratios, estimating, percentages, weight, length, piecharts, pictograph, bar graph, mode, median, mean & range aswell as Geometry & Algebra.
Seriously.
Roman used Microsoft Works spreadsheet to produce a pie chart, which he showed Smurf how to do too. They chose to present all their findings as a long thin poster, printed-out from the computer.
The 'Zorro' looking 'Z' at the bottom of their poster is shown below in close-up with pasted text so's you can understand what the picture's all about! (maybe)...
No 11. Geometry.
If jelly beans are arranged into lines and angles, how can we prove them congruent? First let’s understand some definitions.
Parallel Lines: Two or more lines that are the same distance from each other, all the way along their lengths.
Transversal: A straight line that crosses over two or more lines.
Interior angles: Angles that are on the inside of two lines.
Exterior angles: Angles that are on the outside of two lines.
Congruent: Angles or lengths that have the same measure.
Corresponding angles: A pair of nonadjacent angles lying on opposite sides of the transversal.
Supplementary angles: Two angles whose sum equals 180 degrees.
If a transversal intersects two parallel lines, then the alternate interior angles are congruent.
(Angle 3 = angle 6) (Angle 4 = angle 5)
If a transversal intersects two parallel lines, then the corresponding angles are congruent.
(Angle 1 = angle 6) (Angle 2 = angle 5) (Angle 3 = angle 8) (Angle 4 = angle 7)
If a transversal intersects two parallel lines, then the alternate exterior angles are congruent.
(Angle 1 = angle 8) (Angle 2 = angle 7)
If a transversal intersects two parallel lines, then the interior angles on the same side of the transversal are supplementary. (Angle 3 + angle 5 = 180 degrees) (Angle 4 + angle 6 = 180 degrees)
^^^ 'Big Kid' maths is like another language!
There was also some personal & social skills involed... namely... 'getting along with your partner', showing tolerance, listening to someone else's ideas, being patient (and long-suffering occasionally)... basically all the fruit of the Spirit as outlined in Galatians 5:22 (!)
Yep... Jelly bean maths was interesting, educational & character-building :)
