Matemáticas de 3er grado (2do trimestre)

This class follows the 3rd Grade 1st quarter class. This class will only run with 2 or more students.

Students will be encouraged to discuss how they solve problems, ask questions, and interact with the teacher and other students in the class.

Day 1: Telling time: how many seconds make a minute? How many minutes make an hour? How many hours in a day? Skip counting by 5's. Telling time to the nearest 5 minutes.
Day 2:Telling time to the nearest minute.
Day 3: Telling time- elapsed time
Day 4: Solve word problems involving time intervals within 1 hour by
counting backward and forward using the number line and clock.
Day 5: Solve word problems involving time intervals within 1 hour by
adding and subtracting on the number line.
Day 6: Round two-digit measurements to the nearest ten on the
vertical number line.
Day 7: Round two- and three-digit numbers to the nearest ten on the
vertical number line.
Day 8: Round to the nearest hundred on the vertical number line.
Day 9: Build and decompose a kilogram to reason about the size and
weight of 1 kilogram, 100 grams, 10 grams, and 1 gram.
Day 10: Develop estimation strategies by reasoning about the weight in
kilograms of a series of familiar objects to establish mental
benchmark measures.
Day 11: Solve one-step word problems involving metric weights within
100 and estimate to reason about solutions.
Day 12: Decompose a liter to reason about the size of 1 liter, 100
milliliters, 10 milliliters, and 1 milliliter.
Day 13: Estimate and measure liquid volume in liters and milliliters using
the vertical number line.
Day 14: Solve mixed word problems involving all four operations with
grams, kilograms, liters, and milliliters given in the same units.
Day 15: Add measurements using the standard algorithm to compose
larger units once.
Day 16: Add measurements using the standard algorithm to compose
larger units twice.
Day 17: Estimate sums by rounding and apply to solve measurement
word problems
Day 18: Decompose once to subtract measurements including three-digit minuends with zeros in the tens or ones place.
Day 19: Decompose twice to subtract measurements including three-digit minuends with zeros in the tens and ones places.
Day 20: Estimate differences by rounding and apply to solve
measurement word problems.
Day 21: Estimate sums and differences of measurements by rounding,
and then solve mixed word problems.
Day 22: Review Telling time and rounding
Day 23: Review measurement
Day 24: Assessment
