Bedtime Math Machine

As part of our bedtime routine, Gloria and I exchange our “favorite part of the day.” Tonight I told Gloria I was proud of how generous she is with her brothers, citing the example of when she gave most of her grape juice to Ezra tonight:

GLORIA: How full was Ezra’s glass?
ME: 3/4, or maybe more like 7/8.
GLORIA: Daddy, what’s an eighth?
ME: Half of a quarter.
GLORIA: So Ezra had 3.5 quarters.
ME: Yes! How did you determine that?
GLORIA: Well, to divide seven in half you take 3 and 3 and split the 1 in half, so then half of seven is 3 1/2, so 7/8 is 3.5 quarters.

I think it’s fair to say she gets the concept of fractions.

How Can You Make Six?

Lauren and Gloria had the following conversation on the way home from ballet today that I’m glad they shared with me:

GLORIA: Mommy, we practiced fact groups at school today.
LAUREN: What is a fact group?
GLORIA: A fact group is when we get a number and have to show all the different ways to make a number.
LAUREN: What is the fact group for six?
GLORIA: 3+3 is 6. And 2+4, and 1+5, 0+6, 5+1, and 4+2.
LAUREN: Yup.
GLORIA: There’s also 7 takeaway 1, and 8 takeaway 2.
LAUREN: Do you guys do subtraction also?
GLORIA: No, but I needed to try more ways to make six.
