  21. 1 whole pizza has been split into 2 equal pieces We write it like this. 1 1 equal part 2 equal parts 2

  22. Please help me cut this Pizza in 4 equal parts

  23. 1 whole pizza has been split into 4 equal pieces We write it like this. 1 1 equal part 4 4 equal parts

  24. Please help me cut this Pizza in 8 equal parts.

  25. 1 whole pizza has been split into 8 equal pieces We write it like this. 1 1 equal part 8 8 equal parts

  26. How would I write the fraction for the parts of the Pizza (shaded in yellow)? How would I write the fraction for the parts of the Pizza (shaded in red)?

  27. What number would be 1/2 of these 12 cubes? 12 Cubes What number would be 1/4 of these 12 cubes? What number would be 3/4 of these 12 cubes?

  28. How could I write the number of dark blue cubes as a fraction? 12 Cubes How could I write the number of red cubes as a fraction? How could I write the number of white cubes as a fraction? How could I right the number of yellow cubes as a fraction?
