3rd Grade Math
Parent Letter
1st Nine Weeks
In an effort to keep parents and guardians informed of the expectations and content
being covered in math class this year, this informational handout will be provided for
each unit within the nine weeks. Its intent is to assist in guiding you in ways to support
your child in deepening their mathematical understanding.
Each nine weeks we will spend time reviewing material taught in prior grades as it
relates to the standards being taught in third grade. Our goal is to keep a balance of
skill based learning along with enhancing our student’s ability to problem solve and
think conceptually. The standards on this parent letter will continue into the 2nd
nine weeks.
Review Material from Prior Grades
1) I can use addition and subtraction within 100 to solve one and two-step word
problems with the unknown in any position. (2.OA.1)
2) I can add and subtract within 500 using concrete models, drawings, and various
strategies. (2.NBT.7)
3) I can measure the length of an object by selecting and using appropriate tools.
(2.MD.1)
4) I can represent whole numbers as lengths and sums and differences on a
number line diagram. (2.MD.6)
5) I can tell time in five minute intervals, write time from five minutes intervals, and
use the terms a.m. and p.m. appropriately. (2.MD.7)
New Material for 3rd Grade
1) I can tell and write time to the nearest minute and measure time intervals in
minutes. (3.MD.1)
2) I can solve word problems involving addition and subtraction of time intervals in
minutes. (3.MD.1)
3) I can measure and estimate liquid volumes and masses of objects using grams
(g), kilograms (kg), and liters (L). (3.MD.2)
4) I can add, subtract, multiply, or divide to solve one-step word problems
involving masses or volumes. (3.MD.2)

Model Drawing (for solving word problems)
Grant has two bottles of Gatorade. One bottle holds 700 milliliters, and the other
bottle holds 475 milliliters.
How many milliliters of Gatorade does Grant have altogether?
?
700
700 + 475 = 1,175 milliliters
475
How many milliliters of Gatorade would Grant have left if he drank 350 milliliters?
700
350
700 - 350 = 350 milliliters

Standard Units (for measuring and estimating liquid volumes and masses)
Students will not be required to convert units of measurement. They will need to
measure and estimate liquid volumes and masses as well as solve one-step word
problems using addition, subtraction, multiplication, and/or division.
The most common units of measurement for mass are grams (g) and kilograms (kg).
The most common units of measurement for liquid volume are milliliters (mL) and
liters (l/L).
This holds
about 10 drops
or 1 milliliter
(mL).
About 1 liter (l/L).
