In studying this unit you have explored how using manipulatives can help students to understand how the formal addition and subtraction algorithms work. The manipulatives help students to have a real picture of what they are doing as they regroup ones into tens in addition and as they decompose tens into ones in subtraction.
You have also considered how talking can help students explore their understanding of the decimal number system.
Requirements for teaching from NCF (2005) and NCFTE (2009) were used as ambitious goals.
