1. Build and record three-digit numbers with base-ten blocks and write the number in standard and expanded form.
2. Compare and order up to four three-digit numbers using >, <, = and a number line or hundred chart.
3. Decompose a three-digit number into hundreds, tens, and ones in more than one way (e.g., 12 tens + 6 ones).
4. Identify the value of each digit in a three-digit number and explain how place affects value using a place-value chart.
1. Recall from memory sums and differences within 20 using strategies such as make ten, doubles, and fact families.
2. Add and subtract two-digit numbers with and without regrouping using base-ten drawings or blocks; record the matching equations.
3. Represent addition and subtraction on a number line or hundred chart to justify strategies.
4. Solve one- and two-step word problems within 100 with unknowns in all positions; write and check an equation using the inverse operation.
1. Create equal groups with counters and write the matching repeated addition equation (e.g., 4 groups of 3 = 3+3+3+3).
2. Arrange arrays up to 5 by 5 and determine the total using skip counting or repeated addition.
3. Share up to 20 objects equally between 2, 3, or 4 groups and identify any leftovers; describe the fair-share result.
4. Solve word problems involving equal groups and arrays using drawings and equations with a symbol for the unknown.
1. Measure object lengths to the nearest inch and centimeter using a ruler; label measurements with correct units.
2. Estimate the length of classroom objects before measuring and compare estimates to actual measurements.
3. Compare two lengths and state how much longer or shorter one is using subtraction.
4. Use a number line diagram to add or subtract lengths to solve word problems and show jumps that match the computation.
1. Read and write times to the nearest five minutes on analog and digital clocks; indicate a.m. or p.m. when appropriate.
2. Draw clock hands to match given digital times and explain the meaning of the hour and minute hands.
3. Count mixed sets of pennies, nickels, dimes, quarters, and $1 bills using skip counting by 5s and 10s; write amounts using $ and ¢ symbols.
4. Solve real-world problems involving time and money by modeling with clocks or coins and writing an equation with a symbol for the unknown.
1. Gather data by conducting a simple survey and record results with tally marks.
2. Construct picture graphs and bar graphs with a scale of 1; include titles, labels, and a key when needed.
3. Interpret graphs to determine totals, compare categories, and find how many more or fewer.
4. Pose and answer questions about the data using addition and subtraction within 100.
1. Identify and describe attributes of triangles, quadrilaterals, pentagons, hexagons, and cubes using terms sides, vertices, faces, and edges.
2. Build and decompose composite shapes using pattern blocks or geoboards; name the shapes used.
3. Partition rectangles into equal rows and columns and count all squares to find the total.
4. Partition circles and rectangles into halves, thirds, and fourths and describe the size of shares relative to the whole using appropriate vocabulary.
