In this scenario, the children have the opportunity to develop fluency in multiplying and dividing by 10, 100 and 1000 whilst exploring the inverse relationship between them and equivalency. As a starting point, a cycle of 4 operations brings up some key ideas and allows for further expansion. Although you could go further and give them the opportunity to multiply and divide by powers of … Continue reading What if we created a cycle of multiplying and dividing by 10/100 and 1000?
