There are two Add The Room Sweet Treats Centers in this product. Each set has ten task cards and a recording sheet. The sums are up to 10. Students will count the sprinkles on each treat to determine how many and then add them together to get the sum. Task cards come with and without QR Codes. To access the QR code on the cards you will need to download a free QR reader on your iPad, iPhone, iPod touch. This is a great, easy way to integrate technology into center time.
