Love this! Learning from your mistakes and choosing to br make them again (or at least trying your very best to not make them again) is all part of growing up and being mature and responsible. Doesn't mean you think you are better than other. Just means you want to be better than the person you were yesterday.
Cute Venn diagram to show who has siblings in the class. This would be great to extend into questions such as "How many children have at least one brother?" "How many children have at least one sister?" etc. . . .
Microwave Chewy Chocolate Chip Granola Bars - these taste even better than the boxed kind and they are so easy to make (the coating is made in the microwave), and they can be made with coconut oil or butter (both versions are delicious). You'll want to make them at least once a week!
