Making Sense of Math

AISD Parent Newsletter for the 3rd six weeks

Each six weeks teachers meet together to analyze the Student Expectations (SEs) being taught. They meet with a consultant and discuss what is taught and how to teach it. These meetings are called "Rollouts". Consider this newsletter a "Parent Rollout".


This newsletter is intended to give parents an idea of what is being covered each six weeks in math and what their students should be learning.


Here are links to the first two six weeks newsletters. Please visit them to access vocabulary you may need.

Kindergarten

Kinder students have been working with the numbers 1-15. In this six weeks they are introduced to the numbers 11-15.

  • Students count forward and backward to 15 with and without objects, as well as read, write, and represent the numbers.
  • Students also compose and decompose numbers up to 10 using objects and pictures
  • They compare sets of objects up to 15 using comparative language and generate a set of objects and pictures that is more than, less than, or equal to a given number.
  • When given a number up to 15, students are expected to generate a number that is one more than or one less than the number.
  • Students are expected to recite numbers up to 90 by ones beginning with any number.


In the second unit students develop the foundation of operations.

  • Students use concrete objects, pictorial models, and acting out a situation to model and represent joining and separating problems involving sums and minuends up to 10.
  • Students record their solution using a number sentence and orally explain their solution strategy.
  • As students model, represent, and solve addition and subtraction problems, they begin to develop an understanding of the problem solving process that includes understanding the context of the problem situation and the question being asked, forming a plan or strategy, and using the plan or strategy to determine a solution.

First Grade

During this unit, students extend their knowledge of the base-10 number system by using objects and manipulatives to form multiple groups of tens and ones up to 99.


  • Students compose and decompose numbers through 99 (tens and ones) using concrete objects (base-10 blocks, place value disks, etc.), pictorial models, and numerical representations (e.g., expanded form and standard form).
  • Students use place value relationships to generate numbers that are more or less than a given number using tools such as a hundreds chart and/or base-10 blocks.
  • Students compare whole numbers up to 99 and represent the comparison using comparative language and symbols.
  • Students use open number lines to represent the order of numbers.


During the next unit, students continue delving deeply into the place value system.

  • Students use place value patterns to determine the sum up to 99 of a multiple of 10 and a one digit number, as well as determining a number that is 10 more or 10 less than a given number.
  • Students develop the understanding of cardinal numbers (numbers that tell "how many"

Second Grade

Students analyze attributes of two-dimensional shapes and three-dimensional solids in order to develop generalizations about their properties. Students:


  • classify and sort polygons with 12 or fewer sides by identifying the number of sides and number of vertices.
  • examine if the sides are equal in length, and if the corners are square.
  • use attributes based on formal geometric language to classify and sort three-dimensional solids, including spheres, cones, cylinders, rectangular prism (including cubes as special rectangular prisms), and triangular prisms.
  • compose two-dimensional shapes and three-dimensional solids with given properties or attributes.
  • decompose two-dimensional shapes into equal or unequal parts and use geometric attributes to identify and name the resulting parts.


In the next unit, students continue to develop spatial visualization skills. They:


  • analyze the resulting parts to determine if equal parts exist and name the fractional parts using words rather than symbols (e.g., one-half or 1 out of 2 equal parts rather than).
  • discover and explain the relationship between the number of fractional parts used to make a whole and the size of the parts.
  • Using concrete models, students recognize how many parts it takes to equal one whole, and use this understanding to count fractional parts beyond one whole.
  • Students make connections between counting whole numbers and counting fractional parts as well as extend their understanding of hierarchical inclusion, meaning each prior number in the counting sequence is included in the set as the set increases, to include the sequence of fractional parts.

3rd Grade

Students work with fractions less than one in this unit. They understand the numerator as the part and the denominator as the whole. This unit works with denominators of 2, 3, 4 6, and 8.

  • Fractions are represented using concrete objects, pictorial models (including strip diagrams), and number lines.
  • Students explain the unit fraction as one part of a whole that has been partitioned into 2, 3, 4, 6, or 8 parts and use this understanding to compose and decompose a fraction as a sum of unit fractions.
  • Additionally, students represent fractions as halves, fourths, and eighths as distances from zero on the number line. They must also determine a corresponding fraction when given a specified point on a number line.
  • Students also solve problems that involving partitioning an object or a set of objects among two or more recipients using pictorial representations of fractions.



During the next unit, students extend their understanding of multiplication and division and the mathematical relationships between these operations.

  • They represent multiplication and division of a two-digit number by a one-digit number using arrays, area models, strip diagrams, and equations.
  • Students use the commutative (3 x 2 = 2 x 3), associative [ (2 x 3) x 4 = 2 x (3 x 4) ], and distributive [ 2 x (3 +2) = (2 x 3) + (2 x 2) ] properties of multiplication,
  • mental math,
  • partial products, and the
  • standard multiplication algorithm to represent and solve one- and two-step multiplication and division problem situations within 100.

Multiplication problems include determining area of rectangles.


The last unit deals with future financial security as students explore how skills and education needed for jobs may impact potential income. They also deal with how scarcity of resources may impact cost. Students discuss decisions related to planned and unplanned spending including the responsibilities of using credit.

Students list reasons to save and explain the benefits of saving (e.g., saving for college, surviving hard financial times, being prepared for unforeseen expenses, setting goals, etc.). Students also identify decisions regarding charitable giving.

Fourth Grade

Students relate their understanding of decimal numbers to fractions that name tenths and hundredths, and represent both types of numbers as distances from zero on a number line.


  • Along with representing fractions (including those that represent values greater than one) as sums of unit fractions, students decompose fractions into sums of fractions with the same denominator using concrete and pictorial models and record the results with symbolic representations.
  • Students represent and solve addition and subtraction of fractions with equal denominators using objects and pictorial models that build to the number line and properties of operations.
  • Students evaluate the reasonableness of those sums and differences using benchmark fractions 0, , and 1, referring to the same whole.
  • Using a variety of methods to determine equivalence of two fractions underlies students’ abilities to compare two fractions with different numerators and different denominators and represent those comparisons using symbols.





During the second unit, students represent data on a frequency table, dot plot, or stem-and-leaf plot marked with whole numbers and fractions.

Students examine the characteristics of each data representation, as well as compare the similarities and differences between them. This allows students to solve one- and two-step problems using data in whole number, decimal, and fraction form in a frequency table, dot plot, or stem-and-leaf plot.

Observations include questions of association such as linear (positive or negative trend), non-linear, or no association. Students continue to represent situations with tables, graphs, and equations in the form y = kx or y = mx + b, where b ≠ 0. Within a scatterplot that represents a linear relationship, students use the trend line to make predictions and interpret the slope of the line that models the relationship as the unit rate of the scenario.
