npm17: numbers 19 & 20

April 19

take apart and break apart
compose and decompose
flip the cards and roll the dice
to see how this game goes


if the sum is seventeen
color it [rhyme fail]
hang a number on the hook
to balance left and right

race to know it fast by heart
slow down to understand
tell your method: "First I took..."
use your feet AND hands

greater than and less than
hundreds, tens and ones
a rubber band around the sticks
playing math is fun
