2.G.3 Partitioning Shapes and Equal Shares



This 2.G.3 Partitioning Shapes and Equal Shares unit focuses on the Common Core math standards 2.G.3. This asks students to partitioning rectangles, squares, and circles into halves, thirds, and fourths, as well as tell the difference between equal and unequal shares. There are daily lesson plans, whole group activities, partner practice activities, MATH group centers, exit slips, and assessments.

What’s included in the 5 daily lesson plans:

  • Whole group activity
  • Partner practice activity
  • MATH group: Math writing, Apply new skills, Teacher time, Hands-on math (Teacher time is differentiated learning opportunities for remediation, on-level, and enrichment.)
  • Exit slip

2.G.3 Partitioning Shapes and Equal Shares Focus:
–First Day- Equal vs. Unequal Shares
–Second Day- Partitioning Halves
–Third Day- Partitioning Thirds
–Fourth Day- Partitioning Fourths
–Fifth Day- Mixed Practice

Partition circles and rectangles into two, three, or four equal shares, describe the shares using the words halves, thirds, half of, a third of, etc., and describe the whole as two halves, three thirds, four fourths. Recognize that equal shares of identical wholes need not have the same shape.

The 2.G.3 activities that are included in my short answer, centers, printables, and interactive notebooks are similar but have all been changed to fit these lesson plans. The short answers have different prompts and are now part of MATH groups, the printables & interactive notebooks have been updated and are used during the ‘Apply new skills’ part of MATH groups.
