Mooggi is back! This time he is has a pizza shop and needs your help with his business. Numbers Pizza features 3 very fun games that your pre-k and kindergartener will love. You’ll love it to because it will help them learn numbers and counting. Start off by helping Mooggi add toppings to pizzas that have been ordered in his pizza shop. Mooggi tells you how many of each topping is needed and you drag the toppings and build the pizza. Each time a topping is placed, a number appears on top and a group of kids shout out the number to reenforce the count. Next, move on to the Mushroom Challenge. Mooggi will toss a pizza slice in the air with up to 7 mushrooms on it. You’ll need to quickly count the number of mushrooms and select that number at the bottom of the screen. Each time an answer is correct, a group of kids shout out the number to reenforce the count. Get 10 right in a row and Mooggi will add more time to play. Finally, move on to the Toppings Counter. Help Mooggi take a topping inventory of his pizza shop. He will display up to 99 toppings and you simply count them. Each time a topping is counted, a number appears on top and a group of kids shout out the number to reenforce the count.
