Strand: MATHEMATICAL PRACTICES (1.MP)

The Standards for Mathematical Practice in first grade describe mathematical habits of mind that teachers should seek to develop in their students. Students become mathematically proficient in engaging with mathematical content and concepts as they learn, experience, and apply these skills and attitudes (Standards 1.MP. 1–8).
• Grade 1 Unit 2: Developing Base Ten Number Sense (Georgia Standards)
In this unit, students will rote count forward to 120 by counting on from any number less than 120, represent a quantity using numerals, locate 0-100 on a number line, use the strategies of counting on and counting back to understand number relationships and explore with the 99 chart to see patterns between numbers, such as, all of the numbers in a column on the hundreds chart have the same digit in the ones place, and all of the numbers in a row have the same digit in the tens place.
• Grade 1 Unit 3: Operations and Algebraic Thinking (Georgia Standards)
In this unit, students will explore, understand, and apply the commutative and associative properties as strategies for solving addition problems. Share, discuss, and compare strategies as a class. Connect counting on to solving subtraction problems. For the problem 15 7 = ? they think about the number they have to count on from 7 to get to 15. Work with sums and differences less than or equal to 20 using the numbers 0 to 20. Identify and then apply a pattern or structure in mathematics. For example, pose a string of addition and subtraction problems involving the same three numbers chosen from the numbers 0 to 20, such as 4 + 13 = 17 and 13 + 4 = 17. Analyze number patterns and create conjectures or guesses.
• Grade 1 Unit 4: Sorting, Comparing, and Ordering (Georgia Standards)
In this unit students will develop an understanding of linear measurement, measure lengths as iterating length units, tell and write time to the hour and half hour and represent and interpret data.
• Grade 1 Unit 5: Understanding Place Value (Georgia Standards)
In this unit, students will understand the order of the counting numbers and their relative magnitudes, use a number line and 99 chart to build understanding of numbers and their relation to other numbers, unitize a group of ten ones as a whole unit: a ten, and understand that a group of ten pennies is equivalent to a dime.
• Grade 1 Unit 6: Understanding Shapes and Fractions (Georgia Standards)
In this unit, students will study and compose two- and three-dimensional figures, identify basic figures within two- and three-dimensional figures, compare, contrast, and/or classify geometric shapes using position, shape, size, number of sides, and number of angles, solve simple problems, including those involving spatial relationships, investigate and predict the results of putting together and taking apart two- and three-dimensional shapes, create mental images of geometric shapes using spatial memory and spatial visualization, relate, identify, partition, and label fractions (halves, fourths) as equal parts of whole objects and apply terms such as half of, quarter of, to describe equal shares.
