Today we did quite a bit of work with our Abaci.<\/p>\n
<\/p>\n
We learned how to represent multi digit numbers, and how to do simple addition with an abacus.<\/p>\n
Essentially the abacus works by representing each place value as a rung. \u00a0The beads on the bottom row we will think of as ones, the second row as tens, and so on. \u00a0We may adjust this later for some more complex problems, but for now the simple whole number place values will suffice.<\/p>\n

Tonight students have some addition problems that they should do on their abacus. \u00a0They should then write down the process they used to solve the problems on the abacus. \u00a0This is all detailed on the worksheet they received:<\/p>\n
