The first step in teaching subtraction with understanding: Fair Trades Down, a game on trading big things for little things, in this video, trading 1000s for 100s, 100s for 10s, and 10s for 1s with the Ten Land blocks. Go to MOVE IT Math™ on the web @ moveitmaththesource.com for lessons using the Fair Lands™ blocks and Ten Land blocks to teach, with understanding, the concepts of base and place value, how a place value numeration system works, and the operations of addition and subtraction. The site is full of great lessons on basic math -- the arithmetic of work, business, and adult living -- that are effective with ALL children, including those who dont know what they ought to know by now and those who need enrichment. Please give us a chance to help you boost grades, increase test scores, and improve attitudes. EVERYONE can learn and like math. We are new to the web but have been making that happen for more than 35 years!
