Ant receives a special invitation to dinner with Lion. Other animals attend the dinner, but their manners are horrible. When it is time to eat the birthday cake, the animals all take one-half of the birthday cake. When the cake reaches Ant, there is barely a crumb left for her to share with the Lion. She decides to bake another cake for the Lion. Not wanting to be outdone, the other animals decide to bake as well, with Hippo needing to bake 256 peanut butter cupcakes. The book is a good example of demonstrating to students the concept of halving and doubling.--Ministry of Education website.
