 # Big Ideas: Math

Learning Expectations for Grade 1 Math:

NUMBER SENSE AND NUMERATION

• Read, represent, compare, and order whole numbers to 50, and use concrete materials to investigate fractions and money amounts
• Demonstrate an understanding of magnitude by counting forward to 100 and backwards from 20;
• Solve problems involving the addition and subtraction of single-digit whole numbers, using a variety of strategies

MEASUREMENT

• Estimate, measure, and describe length, area, mass, capacity, time, and temperature, using non-standard units of the same size
• Compare, describe, and order objects, using attributes measured in non-standard units

GEOMETRY AND SPATIAL SENSE

• Identify common two-dimensional shapes and three-dimensional figures and sort and classify them by their attributes
• Compose and decompose common two-dimensional shapes and three-dimensional figures
• Describe the relative locations of objects using positional language

PATTERNING AND ALGEBRA

• Identify, describe, extend, and create repeating patterns
• Demonstrate an understanding of the concept of equality, using concrete materials and addition and subtraction to 10

DATA MANAGEMENT AND PROBABILITY

• Collect and organize categorical primary data and display the data using concrete graphs and pictographs, without regard to the order of labels on the horizontal axis
• Read and describe primary data presented in concrete graphs and pictographs
• Describe the likelihood that everyday events will happen
