Resources for K.1:
UNDERSTANDING THE STANDARD (for Instructor's use)
• A set is a collection of distinct elements or items.
• A one-to-one correspondence exists when two sets have an equal number of items.
• Strategies for developing the concept of one-to- one matching involve set comparisons without counting. Hands-on experiences in matching items between two sets by moving, touching, and aligning objects, using one-to-one correspondence, enable visual as well as kinesthetic comparisons of the number of items in the two sets.
• Students can also count to make comparisons between two sets without matching the sets, using one-to-one correspondence.
• Students are generally familiar with the concept of more, but have had little experience with the term less. It is important to use the terms together to build an understanding of their relationship. For example, when asking which group has more, follow with which group has less and vice versa.All students should
• Understand how quantities relate to each other, which leads to an understanding of how numbers are related to each other.
The student will use problem solving, mathematical communication, mathematical reasoning, connections, and representations to
• Match each member of one set with each member of another set, using the concept of one-to-one correspondence to compare the number of members between sets, where each set contains 10 or fewer objects.
• Compare and describe two sets of 10 or fewer objects, using the terms more, fewer, and the same.
• Given a set of objects, construct a second set which has more, fewer or the same number of objects.
Teaching the Standard (Activities for students)
Books:
Alfie the Alligator: A Teaching Rhyme About Comparing Numbers. By Sandy Turley. (2008) 32p. HelpsforTeachers, (9780977854844). Gr K+. This great teaching resource personifies math by introducing Alfie the Alligator who is on a quest for the biggest number. Students are introduced to the greater than sign (>) the less than sign (<) and the equal sign (=).
A Math Safari: Greater Than, Less Than, and Equal to. By Joanne Randolf. (2003) 24p. Steck-Vaughn. (9780739876909). Gr. PreK-1. This book takes students on a number discovery journey via an African Safari. The pictures are both adorable and engaging and the content is very informative.
More or Less. By Stuart Murphy. Illus. by David Wenzel. (2005) 40p. Harper Collins, (978-0060531676). Gr K-2. In this fun book, Eddie must guess peoples ages just by asking questions. The consequence for mis-guessing? A swim in the dunk tank! Students will enjoy learning about more and less and just how helpful these concepts can be.
Lessons/Activities/Center Work:
Comparing: Fewer and More. This practice site gives students experience identifying "fewer and more" between two sets of objects. In this case the objects are various pictures, so it is farily visually stimulating, and the site keeps track of the number of right and wrong answers and has a timing feature. Great for a computer station during math class.
Fewer and More. Another practice game, but in this case you have mixed sets. Students are shown a row of colored dots and are asked which color has more or less. This helps students not only develop a sense of more and less, but also of color comparison and grouping.
Kindergarten Math Games. Scroll down to the bottom of the page to find a game you can play with your class in whole or small group settings to reinforce the concepts of less and more. Enjoy the rest of the page for some addition games as well.
More, Fewer, Same. Here's a lesson plan to help teach students more and less. It includes plans for center work as well as whole group instruction. The alligator activity ties in very well with the Alfie the Alligator book mentioned above.
More or Less. Here's a basic game you can pull up online to help students with the concept of "more and less." It utilizes both the numeral and a dot system to help students visualize their numbers in different ways. While it's not that flashy, it does a good job of reinforcing information in a station setting.
Electronic Activities:
Greater or Lesser: In this game students work with numerals and decide which is more and which is less. This is a great game for children who are getting ready to move past using objects.
More or Less: This game has students pick among blocks filled with objects. It takes turns on whether you want more or less in your block, and as the game progresses it gets more difficult. Since there are so many boxes to look at, this site would be great when differentiating for more advanced students.
Understanding More Than, Less Than: This is a little online guessing game where students are to guess a number the computer has chosen (from the stipulations given by either the student or the teacher). This is another game that would be useful in differentiating for more advanced students.
Assessments:
Greater than, Less than Worksheet Creator. This site will help you create your own worksheets to help assess your students knowledge of greater than (more) and less than (fewer). Just select your desired options from the list, create, and print out!
More or Less. Here's a free, printable worksheet that not only reinforces the more or less concept, but also encourages number writing. Especially good if you are doing a solar system unit in science as it it planet themed.
On the Farm Round Up. You'll have to scroll down to this worksheet, but this whole page has lots of useful worksheets for many of the math SOLs.
