B2.8 show simple multiplicative relationships involving whole number rates, using various tools and drawings
Moving forward, it is essential that students learn to think about number relationships multiplicatively! First, they need to develop fact fluency so they can think about number relationships. Regular opportunities are needed throughout the year to practice fluency through count-arounds, fluency games and number strings.
Students need practice working with different tools and models (such as the ones included in these problem sets) to allow them to choose the ones that:
make the most sense to them
allow for greater efficiency
A variety of manipulatives to visualize the relationships within and between numbers, eg...
brown and white snap cubes to relate parts of chocolate syrup to parts of milk
circle counters and rectangle shapes to visualize chairs per table
Bar models
Number lines
Double number lines
