1.1.2. Determining the value of a digit in the ones, tens, hundreds, and thousands place.
1.1.3. Determining the value of a number expressed in expanded notation.
AL.1.2. Number and Operations: Students will apply the operations of addition and subtraction to solve problems involving two-digit numerals, using multiple strategies with and without regrouping.
1.2.1. Demonstrating computational fluency for basic addition and subtraction facts with sums through 18 and differences with minuends through 18, using horizontal and vertical forms.
1.2.2. Interpreting multiplication as repeated addition and division as equal groupings.
1.2.3. Solving multistep addition and subtraction problems originating from real-life experiences.
1.2.4. Justifying the strategy used to solve addition and subtraction problems.
1.2.5. Using an estimate to determine if an answer is reasonable.
AL.1.3. Number and Operations: Students will label equal parts of a whole using 1/2, 1/3, and 1/4.
AL.1.4. Number and Operations: Students will determine the monetary value of sets of coins and bills up to $2.00.
1.4.1. Exchanging coins of equivalent value.
1.4.2. Applying monetary symbols, including dollar, cent, and decimal point .
1.4.3. Recognizing the decimal numbers .10, .25, .50, and .75 as related to money.
AL.1.5. Algebra: Students will create growing patterns.
AL.1.6. Algebra: Students will solve problems using the associative property of addition.
AL.1.7. Algebra: Students will describe change over time in observable (qualitative) and measurable (quantitative) terms.
AL.1.8. Geometry: Students will describe attributes of two-dimensional (plane) and three-dimensional (solid) figures using the terms side, surface, edge, vertex, and angle.
1.8.1. Identifying quadrilaterals, pentagons, hexagons, or octagons.
1.8.2. Identifying line symmetry in plane geometric figures.
1.8.3. Creating designs that exhibit line symmetry.
1.8.4. Recognizing the results of changing the position (transformation) of objects or shapes by sliding (translation), turning (rotation), or flipping (reflection).
AL.1.9. Geometry: Students will describe the route from one location to another by applying concepts of direction and distance.
1.9.1. Following multi-step directions to locate objects.
1.9.2. Reading maps of the school environment.
1.9.3. Using grids for movement between points.
AL.1.10. Measurement: Students will measure length in customary units, including inches, feet, and yards.
1.10.1. Using metric units.
1.10.2. Using appropriate tools, including rulers, yard sticks, meter sticks, or tape measures.
AL.1.11. Measurement: Students will estimate weight and capacity by making comparisons with familiar objects.
AL.1.12. Measurement: Students will tell time to the minute using analog and digital clocks.
AL.1.13. Data Analysis and Probability: Students will create displays, including appropriate labels, for a given set of data using pictographs, tally charts, bar graphs, or single- or double-loop Venn diagrams.
1.13.1. Interpreting graphic displays.
AL.1.14. Data Analysis and Probability: Students will determine if one event related to everyday life is more likely or less likely to occur than another event.
