Our engaging activities are the perfect addition to any listening center, helping children practice numbers and counting—hands on! The center is designed for up to 4 kids to work at once, with 16 write & wipe cards covering 12 different activities, 60 counters…plus a CD that guides kids through each lesson. As children follow along, they use write & wipe cards to count and circle sails, count and color in birds and more! Cards measure 8 1/2" x 11". Write & wipe markers sold separately.
