This example helps students understand the addition algorithm by comparing the steps. Core math concepts include place value addition and carrying. Utilizes GeoGebra commands like TextField and Sequence. Suitable for upper elementary or middle school students.

GeoGebra Commands & Parameters

  1. Textfield(base) → inputBox1
  2. Sequence(Sequence[(t + 10, o), o, 1, base], t, 1, tens_2) → list_4
  3. Sequence(Sequence[(t, o), o, 1, base], t, 1, tens) → list2
  4. Sequence((tens + 1, o), o, 1, ones) → list1
  5. Sequence((tens_2 + 11, o), o, 1, ones_2) → list3
  6. Sequence(Sequence[Sequence[(((h - 1) * 10) + t, o), o, -11, base - 12], t, 1, base], h, 1, hunds_{sum}) → list_{sum3}
  7. Sequence(Sequence[((hunds_{sum} * 10) + t, o), o, -11, base - 12], t, 1, tens_{sum}) → list_{sum2}
  8. Sequence(((hunds_{sum} * base) + tens_{sum} + 1 + ((10 - base) * hunds_{sum}), o), o, -11, ones_{sum} - 12) → list_{sum1}

AI Drawing Prompt Reference

Draw a tens place addition diagram, including two tens places (e.g., 12 and 34), each represented by 12 points, one for each place value. Add these two tens places to get a new tens place (e.g., 46), also represented by 12 points. Show the carry-over process during addition and the final sum.
