4.6 The student will add and subtract whole numbers written in vertical and horizontal form,
choosing appropriately between paper and pencil methods and calculators.
4.9.b The student will add and subtract with decimals through thousandths, using concrete materials, pictorial representations, and paper and pencil; and
4.17.a The student will analyze and compare the properties of two-dimensional (plane) geometric figures
(circle, square, rectangle, triangle, parallelogram, and rhombus) and three-
dimensional (solid) geometric figures (sphere, cube, and rectangular solid
[prism])
4.10.a The student will estimate and measure weight/mass, using actual measuring devices, and describe the results in U.S. Customary/metric units as appropriate, including ounces, pounds, grams, and kilograms
4.10.b The student will identify equivalent measurements between units within the U.S. Customary
system (ounces and pounds) and between units within the metric system (grams
and kilograms)
4.10.c The student will estimate the conversion of ounces and grams and pounds and kilograms,
using approximate comparisons (1 ounce is about 28 grams, or 1 gram is about
the weight of a paper clip; 1 kilogram is a little more than 2 pounds).
4.11.a The student will estimate and measure length, using actual measuring devices, and describe the
results in both metric and U.S. Customary units, including part of an inch (1/2,
1/4, and 1/8), inches, feet, yards, millimeters, centimeters, and meters
4.11.b The student will identify equivalent measurements between units within the U.S. Customary
system (inches and feet; feet and yards; inches and yards) and between units
within the metric system (millimeters and centimeters; centimeters and meters;
and millimeters and meters)
4.11.c estimate the conversion of inches and centimeters, yards and meters, and miles
and kilometers, using approximate comparisons (1 inch is about 2.5 centimeters, 1
meter is a little longer than 1 yard, 1 mile is slightly farther than 1.5 kilometers)
4.12.a The student will estimate and measure liquid volume, using actual measuring devices and using
metric and U.S. Customary units, including cups, pints, quarts, gallons, milliliters,
and liters
4.12.b The student will identify equivalent measurements between units within the U.S. Customary
system (cups, pints, quarts, and gallons) and between units within the metric
system (milliliters and liters)
4.12.c The student will estimate the conversion of quarts and liters, using approximate comparisons (1
quart is a little less than 1 liter, 1 liter is a little more than 1 quart).
4.13.a The student will identify and describe situations representing the use of perimeter and area
4.22 The student will recognize and demonstrate the meaning of equality, using symbols
representing numbers, operations, and relations [e.g., 3 + 5 = 5 + 3 and 15 + (35 + 16) =
(15 + 35) + 16].
