<i>b) HS thực hiện lần lượt các thao tác (tô, nhận xét, nói, viết);</i><br />
+ Tô màu vào hai số trong phạm vi 10. Chẳng hạn: tô màu hai số 3 và 8.<br />
+ Quan sát, nhận xét. 3 đứng trước 8; 8 đứng sau 3.<br />
+ Nói: 3 bé hơn 8; 8 lớn hơn 3.<br />
+ Viết: 3 &lt; 8; 8 &gt;3.<br />
GV chốt: 3 bé hơn 8; 3 &lt; 8.<br />
8 lớn hơn 3; 8 &gt; 3.<br />
<i>c) GV hướng dẫn HS tô màu vào hai số 14 và 17 và so sánh tương tự như trên:</i><br />
14 đứng trước 17; 14 bé hơn 17; 14 &lt; 17.<br />
17 đứng sau 14; 17 lớn hơn 14; 17 &gt; 14.<br />

18 đứng trước 21; 18 bé hơn 21; 18 &lt; 21.<br />
21 đứng sau 18; 21 lớn hơn 18; 21 &gt; 18.<br />
- HS chọn hai số khác và so sánh tương tự như trên, viết kết quả vào phiếu học tập.<br />
<b><i>2. So sánh các số trong phạm vi 60</i></b><br />
Thực hiện tương tự như so sánh các số trong phạm vi 30:<br />
- GV hướng dần HS cắt tiếp ba băng giấy tiếp theo ở Bảng các số từ 1 đến 100, ghép thành một băng giấy đặt trước mặt. GV gắn băng giấy lên bảng:

- GV chọn hai số, chẳng hạn 36 và 42, yêu cầu HS so sánh.<br />
- HS nhận xét:<br />
36 đứng trước 42; 36 bé hơn 42; 36 &lt; 42.<br />
42 đứng sau 36; 42 lớn hơn 36; 42 &gt; 36.<br />
- HS chọn hai số khác và so sánh tương tự như trên, viết kết quả vào phiếu học tập.<br />
<b><i>3. So sánh các số trong phạm vi 100</i></b><br />
Thực hiện tương tự như so sánh các số trong phạm vi 60:<br />
- GV gắn phần còn lại trong bảng các số đến 100 lên bảng (có thể không cần cắt rời)

- GV khoanh tròn vào hai số, chăng hạn 62 và 67, yêu cầu HS so sánh.<br />
- HS nhận xét:<br />
62 đứng trước 67; 62 bé hơn 67; 62 &lt; 67.<br />
67 đứng sau 62; 67 lớn hơn 62; 67 &gt; 62.<br />
- HS chọn hai số khác và so sánh tương tự như trên, viết kết quả vào phiếu học tập.</div>

<h2 style="text-align: justify;"><b>C. Hoạt động thực hành, luyện tập</b></h2>

<div style="text-align: justify;"><b><i>Bài 1</i></b><br />
- HS thực hiện các thao tác:<br />
<i>a) Điền số còn thiếu vào băng giấy.</i><br />
<i>b) So sánh các số theo các bước sau:</i><br />
+ Đọc yêu cầu: 11 18.<br />
+ Quan sát băng giấy, nhận xét: <i>“11 đứng trước 18”,</i> nói: <i>“11 bé hơn 18”</i>, viết <i>“11 &lt; 18”.</i><br />
- Chia sẻ với bạn cách làm. Tương tự HS làm các phần còn lại.<br />
<b><i>Bài 2. Làm tương tự như bài 1.</i></b><br />
<b><i>Bài 3. Làm tương tự như bài 1.</i></b></div>

<h2 style="text-align: justify;"><strong>D. Hoạt động vận dụng</strong></h2>

<div style="text-align: justify;"><b><i>Bài 4</i></b><br />
- Quan sát tranh vẽ, nhận biết bối cảnh bức tranh, đếm số bông hoa mỗi bạn đang cầm, thảo luận với bạn xem ai có nhiều bông hoa nhất, ai có ít bông hoa nhất, giải thích.<br />
GV gợi ý để HS nêu tên các bạn có số bông hoa theo thứ tự từ ít nhất đến nhiều nhất.<br />
- GV chữa bài, khuyến khích HS nêu tình huống so sánh số lượng các đồ vật trong cuộc sống.</div>

<h2 style="text-align: justify;"><b>E. Củng cố, dặn dò</b></h2>

<div style="text-align: justify;">- Bài học hôm nay, em biết thêm được điều gì? Từ ngữ toán học nào em cần chú ý?<br />
- Về nhà, em hãy quan sát xem trong cuộc sống việc so sánh các số trong phạm vi 100 được sử dụng trong các tình huống nào.<br />
<i>(*) Cơ hội học tập trải nghiệm và phát triển năng lực cho học sinh</i><br />
- Thông qua việc so sánh hai số sử dụng quan hệ lớn hơn, bé hơn, bằng nhau và các kí hiệu (&gt;, &lt;, =), HS có cơ hội được phát triển NL mô hình hoá toán học, NL tư duy và lập luận toán học, NL giao tiếp toán học.<br />
- Thông qua việc sử dụng các thẻ số, thẻ dấu (&gt;, &lt;, =), băng số, bảng các số đến 100 để xác định và thể hiện quan hệ lớn hơn, bé hơn, bằng nhau, HS có cơ hội được phát triển NL sử dụng công cụ và phương tiện học toán.<br />
