2.8.a) Estimate the difference; and

2.8.b) Find the difference, using various methods of calculation (mental computation, concrete materials, and paper and pencil).

2.9. The student will recognize and describe the related facts that represent and describe the inverse relationship between addition and subtraction.

2.10. The student will

2.11. The student will estimate and measure

2.11.a) length to the nearest centimeter and inch.

2.11.b) weight/mass of objects in pounds/ounces and kilograms/grams, using a scale.
