Following his counting spree, I decided it was time to show N what 100 & 1000 really means.
First, i took out the unit beads and arranged them like so
I showed N what the numerical of 1000 and 100. When he could identify the two, i laid the cards over each other such that it makes a number in thousands. Here, we made 1140.
N had to bring the correct number of beads according to the numeral we made. Here, its 1144. He had to take out the 1000 beads (the big block on the extreme left), 100 beads (the square shaped in the middle), 40 beads (the 4 ten string beads) and 4 beads (the grey beads at the extreme right).
We played around a few numbers and N had much fun with this! I think he got it too! Whoop!
