Warm
up:
This
was a good warmup even though it’s pretty easy (all you need to do is move
either the left or right triangle to the top (so that two of its vertices would
be touching the two other triangles’ vertices). I set up a couple of these so
that the kids could work in pairs. Then, I had a pair come up and explain what
they did. At some point, the kids had the right solution, but they didn’t
understand that it was the right solution because they thought they only made 4
triangles (they didn’t count the big one).
When I was walking to the Orange Village, I met 5
parents. Each parent had three children. Each child had a friend with them. What
was the minimum number of people walking to Orange Village?
After
a bit of thinking and discussing, they realized that the “I” could’ve been the
only one walking there (since everyone else could be walking the other way)
1)
Pretend
that a policeman came and told you that someone stole a gold chain from a
museum. Facts:
 There are only three people who
could’ve done it Max, Dima, and Sasha (they could’ve done it together with one
of the other suspects but those are the only people that could’ve done it)
 Max never does anything bad without
Dima
 Sasha can’t drive (let’s say they
got there by car)
Was Dima involved?
Thinking…discussing…arguing…
After a couple of minutes, they thought of some possibilities of what could’ve
happened;
1)
If
Max did it, then Dima did it also – in that case, Dima did it
2)
If
Sasha did it, then someone would have to be with him because he can’t drive, so
it could either be Max (who would be with Dima) or only Dima, which, in both
cases, involves Dima
OR…
3)
Dima
did it alone, in which case, well… Dima did it.
Deep
thinking… “These seem to be no other options except the ones we thought of, and
in all the ones we thought of, Dima was involved…” Suddenly the kids’ faces
brighten up “Now the policeman knows who to arrest! Ha!”
Play mancala
with paper plates and poker chips (that way it is more “hands on” because it
bigger than the usual mancala game board)
Very
fun, and it involves math and strategy. We slip up into teams two kids with
me, three kids against us. The kids took turns moving, and we played a couple
rounds, and mixed up the teams (the kids liked it, but they soon got tired of
it).
Make a rectangle out of these pieces (solutions are
included in white/gray):
They
played around with these for a little while, and solved it, afterwards announcing that since they solved it one way
already there was no point in continuing (oh well.)
