Smart Doubling
Second graders use mental math in calculations involving addition and subtraction. They study doubles facts to work out addition problems mentally using part and or whole reasoning.
Curated OER
Rabbits
Students review what they think doubling means and double numbers mentally, for example, 5, 12, 16. They share their solutions and discuss how they doubled. They work together on a problem that is beyond mental working and solve...
