4TH GRADE MATH
WHAT HAVE WE LEARNED SO FAR?
WHAT IS STILL TO COME?
WHAT LESSONS WILL TOPIC 13
COVER?
ESSENTIAL QUESTIONS?
• How can you convert from one unit to
another?
• How can you be precise when solving
math problems?
HIGHER ORDER THINKING
1. What is the difference between mass and
weight?
2. When do we use conversion of units?
3. Why are units important in measurement?
4. Why do we need to be able to convert between
capacity units of measurement?
RECURRING STANDARD
MAFS.4.NBT.2.5 (DOK 2)
Multiply a whole number of up to four digits by a one-digit whole number, and
multiply two two-digit numbers, using strategies based on place value and the
properties of operations. Illustrate and explain the calculation by using equations,
rectangular arrays, and/or area models
MAFS.4.NF.2.3. (DOK 2)
Understand a fraction a/b with a > 1 as a sum of fractions 1/b.
a) Understand addition and subtraction of fractions as joining and separating
parts referring to the same whole.
b) b) Decompose a fraction into a sum of fractions with the same denominator in
more than one way, recording each decomposition by an equation. Justify
decompositions, e.g., by using a visual fraction model. Examples: 3/8 = 1/8 +
1/8 + 1/8 ; 3/8 = 1/8 + 2/8 ; 2 1/8 = 1 + 1 + 1/8 = 8/8 + 8/8 + 1/8.
c) c) Add and subtract mixed numbers with like denominators, e.g., by replacing

MAFS.4.MD.1.1 (DOK 1)
Know relative sizes of measurement units within one system of units
including km, m, cm; kg, g; lb, oz.; l, ml; hr, min, sec. Within a single
system of measurement, express measurements in a larger unit in
terms of a smaller unit. Record measurement equivalents in a two
column table. For example, know that 1 ft is 12 times as long as 1 in.
Express the length of a 4 ft snake as 48 in. Generate a conversion table
for feet and inches listing the number pairs (1, 12), (2, 24), (3, 36

MAFS.4.MD.1.2 (DOK 2)
Use the four operations to solve word problems involving distances,
intervals of time and money, including problems involving simple
fractions or decimals. Represent fractional quantities of distance and
intervals of time using linear models.
MAFS.4.MD.1.3 (DOK 2)
Apply the area and perimeter formulas for rectangles in real world and
mathematical problems. For example, find the width of a rectangular
room given the area of the flooring and the length, by viewing the area
formula as a multiplication equation with an unknown factor.
