Students build their conceptual understanding of what happens when you multiply a decimal by another decimal. The Smartboard uses two colors of overlay tenth "rods" to work out real world scenario problems. This step by step approach particularly helps those students who tend to get lost in multi-step problems. Though the Smartboard consists of 53 total slides, the teacher can use as few or as many as his or her students need. Afterwards, the learning can be reinforced with a Pair Up! game in which students apply their learning by finding the student with their partner card (one partner has the algorithm, the other partner has the model). Let this package help YOU help your students with multiplying decimals by decimals.
