Hamilton's Math Update 1-7-24

Welcome back and Happy New Year! This week, we will continue in chapter 6 talking about decade numbers and diving deeper into place value. 

The vocabulary words associated with this chapter are 120 chart, row, column, decade numbers, digit, ones, tens, ones place, and tens place.

Here are a few strategies that you can use with your student to practice understanding the digits of numbers up to 120.

  • Encourage your student to look for numbers wherever you are. Then, review the value of the digits in the tens and ones places. For example, you might notice a speed limit sign, a channel number on TV, or the jersey number of a favorite athlete. Ask your student to name the number, then tell which digit is in the tens place and which is in the ones place. Then ask about the value of each digit. For example, “The 4 is in the tens place in 45. How much is 4 tens? How much is 5 ones?” You can also use these numbers to review counting on by ones or tens. Ask, “What are the next five numbers when you count on by ones? What are the next five numbers when you count on by tens?”
  • Hunt for decade numbers while running errands. See how many you and your student can find on signs, license plates, or price tags. Then have your student tell how many tens are in that number.
  • To practice identifying numbers with a given amount of tens and ones, make stacks of 10 pennies and leave up to 9 pennies unstacked. Model how to count the stacks by tens, then count the leftovers by ones. Have your student do the same, then tell how many pennies in all.

By the end of this chapter, your student should feel confident with the learning targets and success criteria on the next page. Encourage your student to point out and identify any numbers they see up to 120.

Have a great time practicing numbers together!
