This title "From Tally Marks to Diagrams" offers you ready-to-use materials to impart basic statistical knowledge to your students. What is a matrix? How do I create a tally? What can I read from a diagram? With these step-by-step materials, your students will efficiently and sustainably acquire the fundamentals of statistics. Gradually, your students will be introduced to the collection and presentation of data with increasing complexity. After a joint introduction in the classroom, they can work completely independently with the materials. This gives you the opportunity for individual support and encouragement of each student. Materials with three levels of differentiation facilitate the introduction to this important area of probability theory—ensuring that every student becomes a little data researcher.
