Compare Sets of Objects Guided Lesson Explanation

Young mathematicians are on their feet and moving around in this primary grade sorting activity. After giving each child an object or picture card, they then sort themselves into groups, counting to see which has the most or least...

As young scholars begin connecting numbers with values, help them grasp this concept with sets of objects like these. They examine five sets (up to 15 in number) and match each to a corresponding digit. Then, they draw a set of their own...

Capture the engagement of young mathematicians with this hands-on sorting activity. Given a bag of objects, students work independently sorting the items based on their physical attributes, counting to determine the size of each group....

When comparing groups of objects, it's easy for children to identify which has more, but it's not so easy for them to explain their reasoning. This simple whole-group activity provides multiple opportunities for learners to compare...

For many young children it seems obvious that longer objects are heavier than shorter objects. This assumption is put to the test as the class investigates the relationship between length and weight in a whole-group activity. Using a...

Help your young learners master 1:1 correspondence by counting pictured objects, and to communicate answers in multiple choice format. Given a number, they choose which of 3 rows of objects is the correct match. Four opportunities to...

Have your young gardeners practice their counting with a lemon tree that's missing its lemons and a flower that's missing its leaves. Included are the two plants and a set of 10 lemons, 10 leaves, and 10 numbers. See the materials tab...

Practice math vocabulary terms fewer, more, and data using this visual-object-analysis guide. Learners observe three sets of objects and answer three questions, two of which compare numbers of objects, and the last which...

Reinforce number sense with a collection of math lessons for kindergarteners through fifth graders. Young mathematicians take part in hands-on activities, learning games, and complete skills-based worksheets to enhance proficiency...

Ten-frames are great visual tools that support the development of number sense in young mathematicians. A multitude of ten-frames are included in this slide show that provide learners with practice with quickly and fluently identifying...
