1.1 Demonstrate meanings for whole numbers, commonly-used fractions and decimals (for example, 1/3, ¾, 0.5, 0.7), and representing equivalent forms of the same number through sue of physical models, drawings, calculators, and computers.
1.1a Using objects and pictures, represent whole numbers including odds and evens from 0 to 1,000
1.1c Using concrete materials, demonstrate the meanings of fractions including halves, thirds, fourths, eighths, and tenths of sets and wholes ES
1.2 Read and write whole numbers and know place-value concepts and numeration through their relationships to counting, ordering, and grouping. ES
1.2a Read and write numerals from 0 to 1,000 in meaningful contexts
1.2e Write three-digit numbers in expanded form ( for example, 459 = 400 + 50 + 9) ES
1.3 Use numbers to count, to measure, to label, and to indicate location.
1.3a Count from by 1’s, 2’s, 5’s, and 10’s ES
1.3b Count from 1 to 1,000 by 100’s
1.3d Use ordinal positions for first through hundredths
1.3e Sequence selected whole numbers from 0 to 1,000
1.6a Use number sense to estimate sums and differences of fractions and decimals using benchmarks (for example, 5/6 + 7/8 must be equal to an amount less than 2, since each fraction is less than 1).
2.1 Reproduce, extend, create, and describe patterns and sequences using a variety of materials.ES
2.1a Verbally describe patterns in tables and graphs
2.1b Create and extend patterns using symbols such as word and numbers

3.1b Display data using tallies, bar graphs, pictographs, or tables
3.2 Interpret data using concepts of largest, smallest, most often, and middle
3.2a Interpret and compare data from displays using the terms “least often,” “most often,” and “how much more” or “how much less”
4.1 Recognize shapes and their relationships (for example, symmetry, and congruence) using a variety of materials.
4.1c Describe symmetry
4.1d Identify lines of symmetry of squares and rectangles
4.2 Identify, describe, draw, compare, classify, and build physical models of geometric figures.
4.2a Describe the attributes of circles, triangles, and quadrilaterals such as squares and rectangles
Describe, draw, identify, and compare figures
Make models of geometric figures using different materials
Identify applications of geometric concepts in the environment
5.1 Know, use, describe, and estimate measures of length perimeter, capacity, weight, time, and temperature.
5.1a Tell time to the nearest five minutes, using an analog and digital clock ES
5.1i Know the number of hours in a day, months in a year (sequence), inches in a foot, feet in a yard, cups in a pint
5.3 Demonstrate the process of measuring in inches and centimeters. ES
5.4a Read degrees Fahrenheit and degrees Celsius on a thermometer. ES
5.5 Select and use appropriate standard and non-standard units of measurement in problem-solving situations
