These learning engagements are intended to be used with math manipulatives and/or in a guided math group working collaboratively. I recommend that the teacher use questioning to both guide and deepen understandings as students explore the concept of equal groups. The multiple ways to help students both work with and visualize equal groups can be done with cubes, blocks, arrays, and fraction materials including clocks. There are multiple strategies to access and build upon while constructing understandings for additive, multiplicative and proportional reasoning.
SIDENOTE: While watching, Pam Harris' free course, she made a connection to what I have built in equal groups that offers an extension. She refers to building additive and multiplicative relationships. Think about a number like 72 and what ways can we use addition and multiplication to arrive at the 72
