Grade 1 Unit 2: Integrating Areas of Math

What Your Child Will Learn: Unit 2 continues to build on the tasks and work done in Unit 1. In this unit, students will be continuing to work with place value, addition, and subtraction. Students will also begin to understand and define the attributes of shapes, begin to look at data and answer questions about it, and explore more strategies for problem solving. MORE SPECIFICALLY, CHILDREN WILL LEARN HOW TO:

• Solve real-world problems using addition within 20 that involving “putting together” by using objects, drawings and equations.

• Solve real-world problems using subtraction within 20 that involve “taking from,” taking apart, and comparing by using objects, drawings and equations.

• Understand that two digits of a two-digit number represent amounts of tens and ones • Understand that the numbers 10, 20, 30, 40, 50, 60, 70, 80, 90 refer to one, two, three, four,

five, six, seven, eight, or nine tens (and 0 ones). • Understand the meaning of the equal sign. • Distinguish between defining attributes and non-defining attributes. • Add within 20, using mastery of adding within 10. • Use the relationship between addition and subtraction as a strategy. • Use equivalent sums as a strategy. • Compare two two-digit numbers using the tens and ones digits. • Interpret data with up to three categories. • Ask questions about the total number of data points. • Ask questions about number of data points in each category. • Answer questions about how many more or less in one category vs. another.

Standards:

Part A: 1.NBT.2, 1.NBT.3, 1.OA.7 Part B; 1.OA.1, 1.OA.6 Part C: 1.G.1, 1.MD.4

For more information on the strategies, standards and explanations, visit the California Framework at: http://www.cde.ca.gov/be/st/ss/documents/ccsmathstandardaug2013.pdf Some samples of the type of problems your child will be seeing in this unit: SAMPLE 1: 8 + 7 = ___

Student 1: Making 10 and Decomposing a Number I know that 8 plus 2 is 10, so I decomposed (broke) the 7 up into a 2 and a 5. First I added 8 and 2 to get 10, and then I added the 5 to get 15. 8 + 7 = (8 + 2) + 5 = 10 + 5 = 15

Student 2: Creating an Easier Problem with Known Sums I know 8 is 7 + 1. I also know that 7 and 7 equal 14 and then I added 1 more to get 15. 8 + 7 = (7 + 7) + 1 = 15

Example: 14 – 6 = ___

Student 1: Decomposing the Number You Subtract I know that 14 minus 4 is 10 so I broke the 6 up into a 4 and a 2. 14 minus 4 is 10. Then I took away 2 more to get 8. 14 – 6 = (14 – 4) – 2 = 10 – 2 = 8

Student 2: Relationship between Addition and Subtraction 6 + � is 14. I know that 6 plus 8 is 14, so that means that 14 minus 6 is 8. 6 + 8 = 14 so 14 – 6 = 8

Most addition and subtraction will be done in the context of a word problem. Encouraging students to make up their own story problems can help them apply different context to their mathematical thinking. SAMPLE 2: Put the correct symbol on the line. (<, >, or =) 42 ___ 45

SAMPLE 3: What is your favorite flavor of ice cream? Chocolate 12 Vanilla 5 Strawberry 6

Students interpret the data by comparing categories. Examples of comparisons:

What does the data tell us? Does it answer our question? More people like chocolate than the other two flavors. Six people liked Strawberry. 7 more people liked Chocolate than Vanilla. The number of people that liked Vanilla was 1 less than the number of people who liked Strawberry. The number of people who liked either Vanilla or Strawberry was 1 less than the number of people who liked chocolate. 23 people answered this question.

Activities at Home:

• Encourage your child to use more than one method of solving an addition or subtraction problem.

• Roll 1 or 2 dice and make a two-digit number. (Have them write them down and compare or put them in order!)

• Practice adding or subtracting numbers up to 10 to build fluency. • Make 10 stacks of Legos or blocks and practice counting by 10. You can do this for 2 and 5 to

extend and challenge them too! Learning Links:

Student 1: 42 has 4 tens and 2 ones. 45 has 4 tens and 5 ones. They have the same number of tens, but 45 has more ones than 42. So 45 is greater than 42. So, 42 < 45.

Student 2: 42 is less than 45. I know this because when I count up I say 42 before I say 45. So, 42 < 45.

Distrito Escolar Unificado de Glendale Carta a los padres

1.er Grado Unidad 2: Integración de las áreas de las matemáticas

Lo que su hijo aprenderá: La unidad 2 sigue basándose en las tareas y el trabajo realizado en la Unidad 1. En esta unidad los estudiantes continuarán trabajando con el valor posicional, la suma y la resta. Los estudiantes también empezarán a entender y definir los atributos de las figuras, empezarán a analizar los datos y contestar preguntas sobre ellos y explorar más estrategias para la resolución de problemas. MÁS ESPECÍFICAMENTE, LOS NIÑOS APRENDERÁN CÓMO:

• Resolver problemas de la vida real usando sumas hasta 20 aplicando la técnica de "juntar" mediante el uso de objetos, dibujos y ecuaciones.

• Resolver problemas de la vida real utilizando la resta hasta 20 aplicando la técnica de "tomando de", separando, y comparando mediante el uso de objetos, dibujos y ecuaciones.

• Comprender que los dos dígitos de un número de dos dígitos representan cantidades de decenas y unidades

• Comprender que los números 10, 20, 30, 40, 50, 60, 70, 80, 90 se refieren a uno, dos, tres, cuatro, cinco, seis, siete, ocho, o nueve decenas (y 0 unos).

• Comprender el significado del signo de igual. • Distinguir entre los atributos que definen características y los que no • Sumar menos de 20, utilizando el dominio de la adición de menos de 10. • Usar la relación entre la suma y la resta como una estrategia. • Usar sumas equivalentes como estrategia. • Comparar dos números de dos dígitos utilizando dígitos de decenas y unidades. • Interpretar datos que incluyen hasta tres categorías. • Hacer preguntas sobre el número total de puntos de datos. • Hacer preguntas sobre el número de puntos de datos en cada categoría. • Contestar preguntas sobre cuántos más o menos en una categoría frente a otra.

Estándares:

Parte A: 1.NBT.2, 1.NBT.3, 1.OA.7 Parte B; 1.OA.1, 1.OA.6 Parte C: 1.G.1, 1.MD.4

Para obtener más información sobre las estrategias, normas y explicaciones, visite el Marco de Referencia de California en: http://www.cde.ca.gov/be/st/ss/documents/ccsmathstandardaug2013.pdf Algunas muestras del tipo de problemas que su hijo va a ver en esta unidad: Ejemplo 1: 8 + 7 = ___

Alumno 1: Hacer 10 y descomponer un número Yo sé que 8 más 2 es 10, así que descompongo (parto) 7 en 2 y 5. Primero sumo 8 y 2 para obtener 10, y después sumo 5 para obtener 15. 8 + 7 = (8 + 2) + 5 = 10 + 5 = 15

Alumno 2: Crear un problema más fácil con sumas conocidas Yo sé que 8 es 7 + 1. También sé que 7 y 7 suman 14 and y después añado 1 más para obtener 15. 8 + 7 = (7 + 7) + 1 = 15

Ejemplo: 14 – 6 = ___ Alumno 1: Descomponer el número que restas Yo sé que 14 menos 4 es 10 así que parto 6 en 4 y 2. 14 menos 4 es 10. Después quito 2 más para obtener 8. 14 – 6 = (14 – 4) – 2 = 10 – 2 = 8

Alumno 2: Relación entre la suma y la resta 6 + � es 14. I sé que 6 más 8 es 14, y eso significa que 14 menos 6 es 8. 6 + 8 = 14 así que 14 – 6 = 8

Page 7: What Your Child Will Learn: MORE SPECIFICALLY, CHILDREN … · 2016-09-20 · Glendale Unified School District Parent Letter Grade 1 Unit 2: Integrating Areas of Math What Your Child

La mayoría de las sumas y restas se harán en el contexto de un problema de palabra. Animándolos a idear sus propios problemas de la historia pueden ayudarles a aplicar distintos contextos a su razonamiento matemático. EJEMPLO 2: Coloca que el símbolo correcto en la línea. (<, >, o =) 42 ___ 45

EJEMPLO 3: ¿Cuál es tu sabor de helado favorito? Chocolate 12 Vainilla 5 Fresa 6

Los estudiantes interpretan los datos mediante la comparación de las categorías. Ejemplos de comparaciones:

¿Qué nos dicen los datos? ¿Responden a nuestras preguntas? A más personas les gusta el chocolate más que los otros dos sabores. A seis personas les gusta el de fresa. A 7 más personas les gusta el chocolate que a los que les gusta la vainilla. El número de personas que le gusta la vainilla fue 1 menos que el número de gente que le gusta la fresa. El número de gente al que le gusta ya sea la vainilla o la fresa fue de 1 menos que el número de gente que le gusta el chocolate. 23 personas respondieron a esta pregunta.

Actividades en el hogar: • Anime a su hijo a usar más de un método para resolver un problema de suma o resta. • Tirar 1 o 2 dados para hacer un número de dos dígitos. (¡Haga que los escriba y compare o

los ponga en orden!) • Practicar sumar y restar números hasta 10 para mejorar tu fluidez. • Hacer torres de 10 de Legos o bloques y practicar contando de 10 en 10. ¡También puede

hacerlo de 2 en 2 y de 5 en 5 para ampliar la actividad y hacerla más desafiante! Enlaces de aprendizaje (en inglés):

Alumno 1: 42 tiene 4 decenas y 2 unidades. 45 tiene 4 decenas y 5 unidades. Tienen el mismo número de decenas, pero tiene más unidades que 42. Así que 45 es más grande que 42. Por lo que 42 < 45.

Alumno 2: 42 es menor que 45. Lo sé porque cuando cuento hacia adelanta digo 42 antes de decir 45. Por lo que 42 < 45.
