Grade 2 - Number Sense and Numeration
Standard 2.NSN.1 - Practice counting the total value of a number of coins.
Included Skills: Money
Quantity Relationships • represent, compare, and order whole numbers to 100, including money amounts to 100�, using a variety of tools (e.g., ten frames, base ten materials, coin manipulatives, number lines, hundreds charts and hundreds carpets); • read and print in words whole numbers to twenty, using meaningful contexts (e.g., storybooks, posters, signs); • compose and decompose two-digit numbers in a variety of ways, using concrete materials (e.g., place 42 counters on ten frames to show 4 tens and 2 ones; compose 37� using one quarter, one dime, and two pennies) (Sample problem: Use base ten blocks to show 60 in different ways.); • determine, using concrete materials, the ten that is nearest to a given two-digit number, and justify the answer (e.g., use counters on ten frames to determine that 47 is closer to 50 than to 40); • determine, through investigation using concrete materials, the relationship between the number of fractional parts of a whole and the size of the fractional parts (e.g., a paper plate divided into fourths has larger parts than a paper plate divided into eighths) (Sample problem: Use paper squares to show which is bigger, one half of a square or one fourth of a square.); • regroup fractional parts into wholes, using concrete materials (e.g., combine nine fourths to form two wholes and one fourth); • compare fractions using concrete materials, without using standard fractional notation (e.g., use fraction pieces to show that three fourths are bigger than one half, but smaller than one whole); • estimate, count, and represent (using the � symbol) the value of a collection of coins with a maximum value of one dollar.
