• Start with concrete activities:• Sort objects according to characteristics• Record results of sorting in a table or tally
chart• Create simple graphs with table data using
pencil and paper• Ensure students have a basic understanding of
data handling especially organizing data

Using Spreadsheet Functions
• Formulas = Functions• Functions are built into your
spreadsheet• Common functions are
average, sum, count, mode, mean
• They include a range of numbers or cells
=average(B1:B10)
=sum(A1+E3+D5)
=mode(B9:J11)
Working with Formulas
• Moving formulae- copying and pasting: Click + Drag! Session 3
• What difference does it make? Does moving or copying formulas make a difference? What do you notice about a formula when you copy it?
