Number sense is an important part of mathematics learning, and is essential to our daily lives. Educators often say that they want students to have automaticity with their math facts, but what do they mean by this?
“Automaticity is the quick, fluent and efficient retrieval and use of consolidated math facts. When facts are automatic, they reduce the cognitive load. In the early years and through the grades, it is important to build, develop and support the understanding of number sense by using math models (e.g., 5 rack, 10 rack, math rack, number line, array, relational rods, two-sided counters)... In order to develop complex mathematics, students need to rely on foundational skills to support problem solving and reasoning. Without that, learners will need to access specific supports, tools, strategies and interventions to get to the same understanding.” (Understanding Learning Disabilities: How Processing Affects Mathematical Learning, pg. 12)
So, how can you help your child with this? Here are some strategies you can use to help:
- Estimate before trying to figure out answers to questions.
- Have your child use mental math strategies to build number sense.
- Have your child look to the numbers to make connections and determine the most efficient strategy for the given task.
Primary Task:
Here is a game that you can play with your child to support the development of math facts and fluency:
- Race to 100 (but only have students use addition and subtraction)
- For younger students - instead of race to 100, start with race to 20
Junior Task:
Here are two games that you can play with your child to support the development of math facts and fluency:
Intermediate Task:
Here is a game that you can play with your child to support the development of math facts and fluency:
