**Warm-Up P-____________________________ E-____________________________**

Think back and try to recall what the acronym PEMDAS stands for. P-____________________________ E-____________________________ M-____________________________ D-____________________________ A-____________________________ S-____________________________

**PEMDAS Foldable Cut Cortar Fold Dobla Cut Cortar Cut Cortar**

Cut out the foldable, fold along the center edge, and cut on the dotted lines to create four flaps; finally, glue it into your math journal. Cut Cortar Cut Cortar Fold Dobla Cut Cortar

5
**(and grouping symbols)**

PEMDAS Foldable Label each flap as seen in the example below. Parenthesis (and grouping symbols) Exponents (and roots) Multiply and Divide From left to right Add and Subtract From left to right

6
**PEMDAS Foldable Paréntesis Exponentes Multiplicación y División**

Etiquetar cada solapa con las palabras siguientes. Paréntesis (y símbolos de agrupación) Exponentes (y raíces) Multiplicación y División De izquierda a derecha Sumar y restar De izquierda a derecha

7
**(and grouping symbols)**

PEMDAS Foldable Example Problem: (1 + 3)² ÷ 4 + 1 Parenthesis (and grouping symbols) Exponents (and roots) Multiply and Divide From left to right Add and Subtract From left to right

8
**(and grouping symbols)**

52 ÷ 4 + (70 ÷ 7) = Parenthesis (and grouping symbols) Exponents (and roots) Multiply and Divide From left to right Add and Subtract From left to right

9
**(and grouping symbols)**

(9 + 2) x 3³ = Parenthesis (and grouping symbols) Exponents (and roots) Multiply and Divide From left to right Add and Subtract From left to right

10
**(and grouping symbols)**

(32 ÷ 2) 22 = Parenthesis (and grouping symbols) Exponents (and roots) Multiply and Divide From left to right Add and Subtract From left to right

11
**(and grouping symbols)**

75 – x 1 = Parenthesis (and grouping symbols) Exponents (and roots) Multiply and Divide From left to right Add and Subtract From left to right

12
**(and grouping symbols)**

35 – (44 ÷ 11 x 1) = Parenthesis (and grouping symbols) Exponents (and roots) Multiply and Divide From left to right Add and Subtract From left to right

13
