This is for a one week set of daily number sense activities for 3rd or 4th grade students. This weeks activities focus on the concepts of multiplication, division and place value. Students are engaged with the same types of problems all week long so they develop a familiarity while gaining a deeper understanding of the concepts. Students are also engaged in making arrays to review the 2 times tables in a conceptual context. I will continue to provide additional weeks each week of the school year.
