Part 2 of 2

PÁGINA 5 ¡Restamos en Español! (Subtraction Problems)

10 Problems

1. 20 − 8 = 12 → doce

2. 35 − 10 = 25 → veinticinco

3. 48 − 8 = 40 → cuarenta

4. 60 − 15 = 45 → cuarenta y cinco

5. 72 − 12 = 60 → sesenta

6. 90 − 40 = 50 → cincuenta

7. 100 − 25 = 75 → setenta y cinco

8. 83 − 33 = 50 → cincuenta

9. 67 − 19 = 48 → cuarenta y ocho

10. 96 − 6 = 90 → noventa

PÁGINA 6 ¡Misiones Matemáticas! (Word Problems)

Story Problems & Reto

Misión 1: 24 + 16 = 40

En español: cuarenta

Misión 2: 75 − 25 = 50

En español: cincuenta

Misión 3: 38 + 12 = 50

En español: cincuenta

Misión 4: 100 − 30 = 70

En español: setenta

Reto Creativo (Sample solutions): 60 + 40 = 100, 120 − 20 = 100, 50 + 50 = 100.
En español: cien.

PÁGINA 7 ¡El Reto Final! (Cumulative Review)

Partes 1, 2 y 3

Parte 1 (Tabla):

Sumas: 18+12=30, 45+20=65, 80+15=95, 65+35=100

Restas: 18−12=6, 45−20=25, 80−15=65, 100−35=65

Parte 2 (Identificación de números):

veinticinco → 25

setenta y tres → 73

noventa y nueve → 99

Parte 3 (Sample Complete Math Sentences):

“Veinte más quince es igual a treinta y cinco.” (20 + 15 = 35)
“Cincuenta menos diez es igual a cuarenta.” (50 − 10 = 40)

Formative Assessment & Extension Tips:

Oral Check: Have students read aloud 3 problems to check pronunciation of tricky sounds (e.g. c / z in “diez”, “once”).

Extension: Challenge fast finishers to write their own two-step word problem in Spanish (e.g., “Tengo 10, gano 5 y pierdo 3...”).
