You can break one of the toothpicks in half.
Stick with coins.
Beck, whatās with your knowing ASL?
That would be fine. We then introduce into her education the concept of fractions, and then point out that the concept of āevenā and āoddā numbers applies only to integers. Win-win, and learning moves forward! 
With all due respect to Beck, a grandchild of hers is going to be working on a way out of the problem rather than understanding a numerical concept.
I donāt speak with my voice often.
I have an impediment that caused stuttering and confusion (in my syntax).
Itās easier with my family and friends for me to do brief ASL. Especially when thereās a group.
I hear fine. Iām just quiet.
Funny, thoā, usually I can talk comfortably with the kids, pets and a few trusted adults.
Youāve obviously never seen her.
Hey, I resemble that statement!
Etymology of the word. No āevenā except in Dutch. The word isnāt the thing. āEducateā has ācatā in it but isnāt a cat.
I once worked with a kid who wanted to learn a little Latin after peering over my shoulder while I was doing my own homework. The sentence in my textbook was āLesbia filia Corneliaā (Lesbia [is] Corneliaās daughter). The kid says, āSo theyāre lesbians.ā I asked how she arrived at that, and she said, āBecause she feels Cornelia!ā
Ok. She will have to āask a parent(not a grand~ one)ā for that talk.
Kids be weird.
How did she do with āelevenā?
I didnāt ask. I actually thought of it at the time.
Didnāt want to add to the conversation.
While youāre there, be sure to explain that seven and several are not the same thing (well, except when they are, but they are not guaranteed to be the same value).
And you said you donāt do math.
I usually explain to kids that even numbers divide by 2 with no remainder.
3 gum drops. I give the kid 2 then thereās 1 remaining. 7 gum drops, give three kids 2 pieces each. Thereās 1 remaining. Odd
Start with six peppermint candies. Give 2 each to three kids. Hey! Nothing remaining. All gone. Even
Thatās the simplest way I could explain it to a child. But they would have a huge sugar rush afterwards. 
Well, I do know how to spell.
Not that youād know it by my typo count on the Dope.
Yeah, no. I donāt do candy.
Iām not that grand-parent.
Cookies?
She totally understands the numeral 7. She will be age 7 soon. Believe you me she knows that number.
Itās the word seven that bugged her.
This would be an excellent counter-point for the O.P. to present to her granddaughter.
