One Hundred Eggs

ONE HUNDRED (100) EGGS

The New Common Core Standards

In Grade 3, instructional time should focus on four critical areas:

(1) developing understanding of multiplication and division and strategies for multiplication and division within 100;

(2) developing understanding of fractions, especially unit fractions (fractions with numerator 1);

(3) developing understanding of the structure of rectangular arrays and of area; and

(4) describing and analyzing two-dimensional shapes.

The one hundred egg activity is a cognitive tool.  It provides a concrete model involving one hundred stand-up eggs (wooden) that allows the learner to explore several concepts that require mastery by the end of grade 3.

  • Multiply and divide within 100
  • Understand properties of multiplication and the relationship between multiplication and division
  • Rectangular arrays
  • Fluency – multiplication up to 100 (the times table)
  • Describing and analyzing two-dimensional shapes

The 100 eggs activity can be used for all four areas identified by the new common core standards.  One hundred eggs involve hands-on, visual representations that with practice may result in long term memory recall.  If you are working at home with your child, we suggest that money or 100 pennies would serve the purpose.
