Key Concepts

  • Comparing quantities
  • Identifying 'how many more'
  • One-to-one correspondence

Learning Objectives

  • Students will be able to compare two groups of objects (up to 10) and identify which group has more.
  • Students will be able to determine 'how many more' objects are in one group compared to another using visual aids.
  • Students will be able to explain their reasoning for determining 'how many more'.

Educator Instructions

  • Introduction (5 mins)
    Begin by reviewing counting to 10 with the students. Ask them to count objects around the room (e.g., pencils, crayons). Introduce the concept of comparing groups and asking the question, 'Which group has more?'
  • Video Viewing (7 mins)
    Watch the YouTube video 'Grade 1: Math Lesson #81 Identifying How Many More' together as a class. Pause at different points in the video to ask questions and encourage student participation. Emphasize the strategy of pairing up blocks to see which have 'no partner'.
  • Guided Practice (10 mins)
    Using blocks, LEGOs, or other manipulatives, create pairs of towers (groups). For each pair, guide students through the process of comparing the towers and determining 'how many more' are in the taller tower. Encourage them to use the 'partner' strategy from the video.
  • Independent Practice (8 mins)
    Give each student a set of manipulatives and ask them to create their own pairs of towers. Have them record their findings on a worksheet, writing down the number of blocks in each tower and how many more are in the taller tower. For example: Tower 1: 5 blocks, Tower 2: 8 blocks, Tower 2 has 3 more blocks.

Interactive Exercises

  • Partner Up!
    Students work in pairs. Each student creates a tower of blocks (up to 10 blocks). They compare their towers and determine who has more and 'how many more'. They then switch roles and repeat.
  • Class Tower Challenge
    Divide the class into small groups. Each group creates a tower of blocks. The groups compare their towers. The group with the tallest tower explains how many more blocks they have than the other towers.

Discussion Questions

  • How can you tell which tower has more blocks just by looking?
  • What strategy did the video show us for finding out 'how many more'?
  • Can you think of other things we can compare besides blocks?

Skills Developed

  • Counting
  • Comparing
  • Problem-solving

Educational Standards

CCSS.Math.Content.1.OA.A.1:Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem. CCSS.Math.Content.1.MD.C.4:Organize, represent, and interpret data with up to three categories; ask and answer questions about the total number of data points, how many in each category, and how many more or less are in one category than in another. CCSS.Math.Content.1.OA.C.5:Relate counting to addition and subtraction (e.g., by counting on 2 to add 2).
