Grade 1 Mathematics Weeks 13–14: Student Textbook
Ten instructional days. Use counters, ten-frames, base-ten blocks, a ruler of equal-size units, and an analog clock where appropriate. Show how you know.
Day 61: Length with same-size units
Learn: Measure with equal-sized cubes or clips placed end to end. There must be no gaps or overlaps. Always name the unit.
Worked example (different from today’s practice): If a strip spans 9 equal cubes, its length is 9 cube units.
Try the four matching practice questions independently. Use counters, drawings, or a number line, and explain one answer.
Day 62: Compare lengths
Learn: Compare lengths using the same-sized measuring unit. Align the objects at the same starting point, then compare their counts.
Worked example (different from today’s practice): A green ribbon measures 13 equal cubes and a yellow ribbon 4 cubes. Green is 9 cubes longer.
Try the four matching practice questions independently. Use counters, drawings, or a number line, and explain one answer.
Day 63: Time to hour
Learn: At a whole hour, the minute hand points to 12. The hour hand points to the hour number. Read both hands to tell the time.
Worked example (different from today’s practice): When the hour hand points to 4 and the minute hand to 12, the time is 4:00, four o’clock.
Try the four matching practice questions independently. Use counters, drawings, or a number line, and explain one answer.
Day 64: Time to half hour
Learn: At half past an hour, the minute hand points to 6. The hour hand sits between the current hour and the next.
Worked example (different from today’s practice): Half past three is 3:30. The hour hand is between 3 and 4.
Try the four matching practice questions independently. Use counters, drawings, or a number line, and explain one answer.
Day 65: Measurement review
Learn: Choose the same measuring unit for length comparisons, and read a clock by looking at both hands. Review which units and labels belong with each answer.
Worked example (different from today’s practice): A ribbon spans 10 equal clips, so its length is 10 clip lengths.
Try the four matching practice questions independently. Use counters, drawings, or a number line, and explain one answer.
Day 66: Count coin values
Learn: A penny is worth 1 cent and a dime is worth 10 cents. Count the dimes by tens, then add pennies by ones.
Worked example (different from today’s practice): One dime and six pennies are 10 + 6 = 16 cents.
Try the four matching practice questions independently. Use counters, drawings, or a number line, and explain one answer.
Day 67: Organize tally marks
Learn: Tally marks record one count at a time. After four straight marks, a fifth mark crosses them to make a group of five.
Worked example (different from today’s practice): One group of five tally marks and one more mark represents 6 votes.
Try the four matching practice questions independently. Use counters, drawings, or a number line, and explain one answer.
Day 68: Read a picture graph
Learn: A picture graph groups information by category. Read its labels and key before counting symbols or comparing groups.
Worked example (different from today’s practice): A graph shows peaches 9 and oranges 2. Peaches have 7 more votes.
Try the four matching practice questions independently. Use counters, drawings, or a number line, and explain one answer.
Day 69: Shapes and attributes
Learn: Two-dimensional shapes have sides and corners. Recognize a triangle, a square, and a rectangle by their attributes rather than their orientation.
Worked example (different from today’s practice): A triangle has three straight sides and three corners. Turning it does not change those features.
Try the four matching practice questions independently. Use counters, drawings, or a number line, and explain one answer.
Day 70: Integrated math checkpoint
Learn: A checkpoint combines skills from several lessons. Read the unit carefully: name coin values, clock times, length units, and category counts.
Worked example (different from today’s practice): Two dimes and one penny total 21 cents. Count tens before ones.
