Recently in adding 100s with carrying Category

Megan is now starting to add with carrying. This is not knew as she is doing it in life of Fred.  This program does it in a neat manner. Here's a set of the problems:  3 + 7, 43 + 7, 243 + 7 , that is, it shows the steps in program.  One thing I like with this program is that they have a fun activity. On page 41, she answered problems in a hat that has a letter on it. Then, below, she finds the corresponding answer and above that in a space she puts the letter. Today , it spelled out "Happy Birthday".
