###### 4.MD.A.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), ...*

###### 4.MD.A.1

I can show that I know the relative size of measurement units within one system of units (including km, m, cm; kg, g; lb, oz; l, ml; hr, min, sec).

I can show the measurements in a larger unit in terms of smaller units and record these in a table.

###### 4.MD.A.1

Puedo demostrar que sé que el tamaño relativo de las unidades de medida dentro de un sistema de unidades (incluyendo km, m, cm; kg, g; lb, oz; l, ml; hr, min, seg).

Puedo mostrar las medidas de una unidad mayor en términos de unidades menores, y anotarlas en una tabla.

###### 4.MD.A.2

Use the four operations to solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money, including problems involving simple fractions or decimals, and problems that require expressing measurements given in a larger unit in terms of a smaller unit. Represent measurement quantities using diagrams such as number line diagrams that feature a measurement scale.

###### 4.MD.A.2

I can use the four operations (+, -, x, ÷) to solve word problems involving measurement.

I can solve measurement problems involving simple fractions and decimals.

###### 4.MD.A.3

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.*
