Engaging Reluctant Learners
Some students do not have a lot of interest in sitting and completing the more “academic” centers. They are content to play in the blocks, at the sensory table, or in dramatic play all day and more reluctant to spend time at the math or literacy centers. The trick is to provide centers that are irresistible to attract them to those areas. These little mailboxes are irresistible!

It works! As soon as the preschoolers see the mailboxes, the students will want to count and sort the cards. Choose the right number of mailboxes and cards for your students’ needs.

In addition to practicing one-to-one counting, they are also learning about subitizing, tens frames, tallies and base 10 blocks.
