Bridges in Mathematics Grade 2, Unit 7: Measurement Money & Time
In this unit, your child tells time to the nearest five minutes on clocks with hands and on digital clocks, using a.m. and p.m. They count dollars and coins and solve story problems about money. They also make and read picture graphs and bar graphs. These everyday skills follow the work with bigger numbers and lead into more measuring and data next.

These are real questions from our practice. Tap the speaker to hear one read aloud, or the light bulb for a hint, and talk about the answer together.
Question 1 of 3
The hour hand is on the 8 and the minute hand is on the 12. What is the time?
- 12:40
- 8:00
- 8:12
How you can help
- Ask your child to read the kitchen clock at a few points in the day and to say whether each time is a.m. or p.m.
- Empty a pocket or purse of coins and have your child sort them, then count the total, starting with the quarters and dimes.
- Make a quick tally of breakfast choices or shoe colors in the family, turn it into a bar graph, and ask how many more chose one than another.
Where kids can get stuck
- Reading the number the long hand points to as the minutes, saying 2:04 instead of 2:20.
- Counting each coin as 1 cent, so a quarter, a dime, and two pennies seem worth 4 cents.
- Thinking a nickel is worth more than a dime because the nickel is bigger.

Bobby's Math Club has practice problems that adapt to your child’s level, each with a detailed explanation and an easy-to-follow video, so your child can build confidence in these skills one step at a time.
