2.3 Handling data: pictograms, probability) Reasons for introducing handling data in preschool education: • mathematical literacy, • interdisciplinary connections of mathematics with other areas (science, language, sport, art…) • deeper understanding of the concepts in arithmetic: counting, comparing, adding, subtracting
b) Presenting data (figural) bar chart, simple tables
Different variables: qualitative (color, favorite sport, fruit…), quantitative (shoe size, height…), semi-quantitative (S, M, L, XL…)
c) Topics for handling data in preschool education • my favorite book, • Favorite transport; • Pets; • My favorite food; • Season of our birthdays Within each topic we collect, represent and interpret data. The children must be interested in the area of handling data and the results of our activities must be useful and offer new understanding of everyday life, society and mathematics concepts.
č) Probability • Introduction of simple concepts in probability: possible, impossible, sure… • Children are becoming aware of the relation ‘reason – consequence’.
