Títol: What Concrete Objects Model Addition and Subtraction in 4th Grade

(quins objectes concrets modelen sumes i restes a 4t de primària)

In fourth grade, students begin to explore mathematical concepts through more concrete objects models. This type of learning helps to make abstract ideas easier to understand and build upon.

To introduce addition and subtraction using concrete objects, we can start by having students gather various everyday objects such as apples, oranges, books, or pencils. We can then assign each object a number or label them based on their quantity. Per exemple, we can label one apple as “1,” two apples as “2,” three apples as “3,” four apples as “4,” i així successivament.

A continuació, we can have students work in pairs or small groups to compare and contrast the quantities of each object. Per exemple, one student can say “I have 3 apples and I want to share them with my friend,” while another student can say “I have 4 apples and I want to take one for myself.”

Once students have learned about the concept of quantity, we can move on to understanding how to add and subtract numbers on these objects. Per exemple, if a student has 3 apples and wants to share them with their friend, they would count 3 + 3 = 6 apples. If a student wants to take one apple from another student’s pile, they would count 3 – 1 = 2 apples.

By using concrete objects models like apples and pencils, students can better understand the concept of quantity and basic arithmetic operations. This type of learning can help students develop strong foundation skills that will serve them well throughout their academic career.
