Welcome to Comparing Numbers! – Learn to compare numbers up to 100 – Understand bigger vs. smaller – Bigger numbers have more, smaller have less – Use ‘greater’, ‘less’, ‘equal’ – ‘Greater than’ is >, ‘less than’ is <, 'equal to' is = – Practice with word problems – Solve problems using comparison words | This slide introduces first graders to the concept of comparing numbers up to 100. Start by explaining that numbers can be compared to see which one is bigger or smaller. Introduce the terms ‘greater than’, ‘less than’, and ‘equal to’, and show the symbols that represent these words (>, <, =). Use relatable examples, such as comparing the number of apples in two different baskets, to illustrate these concepts. For the activity, provide word problems that require students to use comparison words to solve. For example, 'If Tim has 47 marbles and Jane has 52 marbles, who has less?' Encourage students to explain their thinking and use the correct symbols in their answers. Prepare to guide them through several examples and ensure they understand how to interpret and solve comparison word problems.

What Does It Mean to Compare Numbers? – Comparing tells us about size – Is one number bigger, smaller, or the same? – We can compare many things – Like numbers, toys, or animals! – Numbers tell us ‘how many’ – Like 10 is more than 8 – Comparing numbers up to 100 – Use words like ‘greater’, ‘less’, or ‘equal’ | This slide introduces the concept of comparison to first graders. Start by explaining that comparing is like playing a game to see what is bigger, smaller, or the same. Use relatable examples, such as comparing the number of apples to oranges they have in their lunchboxes, or the number of students wearing red versus blue. Emphasize that numbers help us count things, and comparing numbers helps us understand ‘how many’ we have in relation to something else. Introduce vocabulary like ‘greater than’, ‘less than’, and ‘equal to’ and use visual aids like number lines or counters to help them grasp the concept of comparing numbers up to 100.

Comparing Numbers Up to 100 – Understanding ‘>’ symbol – ‘>’ means a number is bigger, like 65 > 42 – Understanding ‘<' symbol – '<' means a number is smaller, like 23 < 76 – Understanding '=' symbol – '=' means numbers are the same, like 34 = 34 – Practice with word problems – Use symbols to solve problems like 'Which number is greater, 58 or 59?' | This slide introduces the basic comparison symbols to first graders: greater than, less than, and equal to. Start by explaining each symbol and its meaning. Use relatable examples with actual numbers to illustrate the concept. For instance, compare the number of apples in two different baskets to explain greater than and less than. After explaining the symbols, provide simple word problems that apply these symbols in a practical context. Encourage students to draw pictures or use physical objects like blocks to visualize the comparisons. This will help them grasp the concept of comparing numbers up to 100 in a tangible way. The goal is for students to become comfortable with these symbols and to use them to compare numbers in various situations.

Let’s Compare with Examples! – 45 is greater than 32 – 45 > 32 means 45 has more than 32 – 26 is less than 29 – 26 < 29 means 26 has fewer than 29 – 50 is equal to 50 – 50 = 50 means both are the same | This slide is designed to help first graders understand the concept of comparing numbers through clear examples. Start by explaining that when we compare, we look at two numbers to see which one is bigger, smaller, or if they are the same. Use visual aids like number lines or counters if possible to show the difference in quantity. Encourage students to use their fingers to count if it helps them understand the concept better. After explaining each example, ask students to come up with their own comparisons using toys, snacks, or other classroom items to make the activity engaging and hands-on.

Comparing Numbers: Who Has More Apples? – Tommy and Sally’s apple count – Tommy has 23 apples, Sally has 15 – Who has more apples? – Tommy has more apples than Sally – Understanding ‘greater than’ – ‘Greater than’ means a larger number – Using ‘>’ to compare numbers – 23 > 15 shows Tommy’s apples are greater | This slide introduces students to the concept of comparing numbers through a relatable word problem involving apples. It’s important to use concrete examples that first graders can visualize, like counting apples. The phrase ‘greater than’ is explained, and students learn to use the ‘>’ symbol to compare quantities. Encourage the students to think about the numbers and visualize the difference in the number of apples. This will help them understand the concept of comparison and the use of comparison symbols in math. During the lesson, engage the students with similar examples and encourage them to use the ‘greater than’ symbol to compare different sets of numbers.

Understanding ‘Less Than’ Through Word Problems – Comparing cars and bicycles – Count the number of cars – There are 18 cars in total – Count the number of bicycles – There are 25 bicycles in total – Which has fewer? – 18 is a smaller number than 25, so there are fewer cars | This slide introduces the concept of ‘less than’ to first graders through a relatable word problem involving cars and bicycles. Start by reading the problem aloud and asking the students to visualize the two groups of objects. Guide them to count each group and then compare the numbers to determine which is smaller. Emphasize that when one number is smaller than the other, we can say it is ‘less than’ and use the symbol ‘<'. Encourage the students to use this method to solve similar problems and understand that comparing quantities is a part of everyday life. The goal is to make them comfortable with comparing numbers up to 100 and using the correct terminology and symbols to describe their observations.

Understanding Equality in Numbers – Comparing Lisa and John’s stickers – Both have 50 stickers each – 50 stickers is the same as 50 stickers – Yes, because 50 is equal to 50 (50 = 50) – Recognizing when numbers are equal – Equal numbers mean the same amount | This slide introduces the concept of equality using a relatable word problem about Lisa and John’s stickers. It’s important to explain to first graders that when two numbers are the same, we say they are equal. Use real stickers or visual aids to show 50 stickers for Lisa and 50 for John, making it clear that both amounts are the same. Reinforce the concept by showing that 50 = 50, and explain that the equal sign means ‘the same as’. Encourage students to think of other things they have in equal amounts, like fingers on each hand, to further illustrate the concept.

Class Activity: Number Match-Up! – Play a game with number cards – Match cards to compare numbers – Find which number is greater, less, or equal – Work with a partner – Share your findings with the class | This interactive class activity is designed to help first graders understand the concept of comparing numbers up to 100. Provide each pair of students with a set of number cards. Instruct them to draw cards and place them side by side to determine which number is greater, less, or equal. Encourage them to use terms like ‘greater than’, ‘less than’, and ‘equal to’ when comparing. After they have matched and compared their numbers, ask them to share their findings with the class. This will not only reinforce their understanding but also develop their communication skills. Possible variations of the activity could include using number cards to create a number line, playing a ‘war’ card game where the higher number wins, or having a ‘number hunt’ where students find objects in the classroom that represent different numbers.
