Hi Suzukimom,
Each level does have consumable worksheets.
My 3rd yr and 1st yr. boys started in Level B together. One suggestion is to get two marker boards so that each boy can write their answers on the board and show you…that way they can answer independently and not hear what the other said and then say the same thing. Also make sure you have two abacus’s….each student should have their own if you are teaching them together.
When you teach them to recongnize the numbers on your hand make sure you have them start with their left hands…we read from left to right.
Just focusing on recognizing quantities up to ten is enough to do right now. Using your hands….use objects around the house….remember when showing 4 items…your child should be able to tell you four without counting…
When using sticks to show quantity help your child to see when they get to five sticks….that five has a middle and four doesn’t. This helps them recognize five. After the child can recognize five you can lay down four sticks and place the fifth stick across the other four….so then when you start workin on six your child can immediately see 5.
RS doesn’t start teaching the abacus till the child can recongnize quantities of 1 – 10 on fingers, with objects and with sticks.
Knowing this will help your children zoom through the first few lessons once you get it.
