Numeracy and confidence are at the heart of math success
Confidence and competency in basic arithmetic lies at the heart of success in math. We believe every kid is capable of mastering arithmetic. However, it is critical that both a good conceptual understanding and a fair degree of proficiency and confidence is established in each skill area before moving on to harder topics. In math, skills build on each other.
Numbers and operations activities
Numbers and operations starts with simple number recognition and counting, moves to larger numbers and place value concepts and then continues through the 4 operations to fractions, decimals, percents and concepts around ratios and factoring.
